Abstract

The utility model relates to medical equipment, in particular to a laparoscopic traction clip used in laparoscopic surgery, which is composed of a clip body (1), a pulling wire (2), and a long straight needle (3). The tail end of the handle is shaped on a straight hole (12), and one end of the pull wire (2) is tied to the hinge shaft in the middle of the clip body (1), and the other end is tied to the long straight needle (3). Because the utility model can directly manipulate the clamp body by inserting the clamp head of the separation forceps into the straight hole of the clamp handle, the tissue that needs to be pulled or held can be controlled and clamped in vitro through the pull wire and the long straight needle, which avoids the traditional use of wire The disadvantages of the ligation or suture method, and the clamping position can be changed at will, and the operation is convenient; only two small holes for the laparoscope and the surgical knife are opened in the patient's abdomen, which reduces the patient's surgical pain and reduces the number of scars; Improve surgical efficiency and quality, but also reduce patient costs.

Description

laparoscopic traction clip

technical field

The utility model relates to medical equipment, in particular to a traction clip used in laparoscopic surgery.

Background technique

Laparoscope is a kind of endoscope. Under the illumination of a good cold light source, the camera system takes pictures of the organs in the pelvis and abdominal cavity on the monitor screen through the laparoscope body connected to the pelvis and abdominal cavity. Under the monitoring and guidance of the monitor, surgical instruments are manipulated outside the abdominal cavity to perform operations such as exploration, electrocoagulation, hemostasis, tissue separation, incision, and suture on diseased tissue. Using laparoscopic technology, the doctor only needs to make a few small holes around the patient's surgical site, and can visually observe the patient's internal situation in front of the computer screen without performing a laparotomy, and perform precise surgical operations. It has the advantages of short operation time, small trauma, safety and recovery The advantage of being fast. However, this kind of operation still has disadvantages: the organ to be operated must be pulled or fixed or held in order to operate the surgical instrument. The traditional method is to first ligate or suture the gallbladder with a thread, and then use a needle to penetrate the abdominal wall to close the gallbladder. The thread is drawn out of the body and pulled by hand. The disadvantage of this method is that it is time-consuming to ligate or suture tissues in the abdominal cavity. For example, when suturing the gallbladder, it may sometimes cause bile overflow, which is not conducive to the operation; the position cannot be adjusted after ligation. If you want to adjust the position, you must ligate or suture again. tie. Therefore, it is generally necessary to open at least three small holes with a diameter of about 1 cm in the abdomen of the patient for the insertion of the laparoscope, the holder or holder of the surgical site tissue, and the surgical knife, and the cooperation of multiple assistants is required; Generally speaking, there will be at least three scars, which will affect the appearance of the body.

Utility model content

The purpose of the utility model is to provide a laparoscopic traction clip, which can reduce the number of openings, reduce the pain of patients, and improve the efficiency and quality of operations.

The technical solution adopted by the utility model is: a laparoscopic traction clamp, which is characterized in that a straight hole is formed at the tail end of the clamp handle of the clamp body, and one end of the pull wire is tied to the hinge shaft in the middle of the clamp body, and the other Tie at one end to a long straight needle.

The length of the pulling line is 20-30cm, and the material is polypropylene suture.

The straight hole at the tail end of the clamping handle is integrally formed by injection molding, or is connected with a pipe thread.

The clamping surface at the front end of the clamp body is made into a tooth-shaped meshing structure, and the tip of the tooth is made into an arc shape.

The clip body has a length of 3-5 cm and a transverse dimension of 0.8-1 cm.

In the utility model, since the tail end of the clip handle is provided with a straight hole, the clip head can be inserted into the straight hole of the clip handle to directly manipulate the clip body under the laparoscopic operation environment, and the tissue that needs to be pulled or held In vitro controlled clamping by pulling wires and long straight needles avoids the disadvantages of traditional thread ligation or suturing methods, and the clamping position can be changed at will, which is convenient to operate; Laparoscopy and surgical instruments can be inserted into small holes, which can reduce the pain of patients and reduce the number of scars; improve the efficiency and quality of operations, and reduce the cost of patients.

Detailed ways

As shown in Figure 1, the utility model is composed of a clip body 1, a pulling wire 2, and a long straight needle 3. One end of the pulling wire 2 is tied to the hinge shaft in the middle of the clip body 1, and the other end is tied Knotted in the long straight needle 3, the material can adopt medical polypropylene suture. The clamp body 1 is similar in structure to the traditional clamp, the difference is that the tail end of the clamp handle 11 is shaped on a straight hole 12 matching the size of the head of the separating pliers 5, and the clamping surface of the front end of the clamp body is made into a tooth-shaped meshing structure to clamp The living tissue is not easy to detach, and the tip of the tooth is made into an arc shape to avoid damage to the tissue. The straight hole 12 of the clamping handle can be integrally formed by injection molding and the clamping body 1, and can also be threadedly connected with the pipe joint 13. The advantage of this is that the pipe joint 13 can be turned upside down to be threaded with the threaded head of the separation clamp 5, while the tail of the clamping handle The end is made into a cylinder, which can meet the requirements of plugging in special cases. Embodiment The length of the clip body 1 is 4 cm, the transverse dimension is 0.9 cm, and the length of the long straight needle 3 is 4-6 cm, whichever can penetrate the thickness of the abdominal wall of ordinary people.

The working principle is shown in Figure 4:

Taking the single-person two-hole cholecystectomy as an example, two holes C and B of about 1 cm are cut on the abdominal wall first, and the hole B is inserted into the laparoscope 4, and the sleeve 6 is installed in the hole C, from the sleeve 6 to the abdominal cavity 7 A preset number of pulling clips are loaded inside, and then the separation forceps 5 are inserted from the cannula 6 into the abdominal cavity 7, and under the guidance of the laparoscope, the head of the separation forceps is inserted into the straight hole 12 at the tail of the clamp body, and the separation forceps are separated. The forceps directly manipulate the tissue clamped by the clamp body 1 on both sides of the preset resection point; withdraw the separating forceps, insert the knotter to penetrate the abdominal wall from the inside to the outside with the long straight needle 3 from D; withdraw the knotter, and then Insert the separation forceps into the tail of the clip body, manipulate the clip body, open the clip to the appropriate position of the gallbladder, pull the gallbladder to an appropriate tension, and clamp the traction wire with the vascular forceps and fix it on the abdominal wall. At this time, the surgeon can operate alone. The gallbladder is removed. The doctor holds the laparoscope 4 with his left hand, and uses separating forceps and other instruments to remove the gallbladder routinely with his right hand. If the position of the gallbladder clamp needs to be adjusted during the operation, the separating forceps can be used to adjust the position of the clamp body before resection. After multiple adjustments, the gallbladder can be removed smoothly, and finally the gallbladder and clip body are taken out from the operation hole of hole C, and the traction clip can be recycled after being sterilized.
