Description
Technical Field
The utility model relates to an adjustable bidirectional elastic fixing abdominal cavity puncture outfit.
Background
With the development and progress of medical science, the traditional open surgery is gradually replaced by new minimally invasive surgery. As the traditional open surgery has been replaced by laparoscopy (3D, 4D, robots), laparoscopic surgery has been successfully applied to general surgery (gastrointestinal, hepatobiliary), urinary surgery, gynecology, etc. surgical departments.
At present, all laparoscopes need to be operated by means of a laparoscope puncture sheath, and generally, each operation needs at least three puncture sheaths (5 mm, 10mm and 12 mm), and 5-6 complex operations are often needed. As in the patent application No. 202311596938.X, the main drawbacks of the current puncture sheath are mainly the following:
1. All puncture sheath is outside, all have one-way screw thread structure (or ladder), when promptly puncture, because this screw thread structure (or ladder) is little to the inside direction, outside slightly big, consequently forward when the sheath gets into, laborsaving, also can not produce the cutting action, but when the operation is finished pulling out the sheath, because with the sheath entering direction just opposite, screw thread structure (or ladder) that comes out this moment is big, consequently appear the screw thread (or ladder) of sheath and human tissue and produce the cutting action, damage tissue, this passageway is less moreover, be difficult for opening hemostasis, once damage great blood vessel or artery, there is secondary big bleeding risk.
2. At present, all sheaths have no fixing device. Because the sheath is hollow, during operation, all surgical instruments need to enter and exit from the sheath core, so that the sheath is easy to drive to enter, exit and move, for example, the sheath moves into the abdominal cavity, and because the overlong sheath is in the abdominal cavity, the movement of the instruments in the abdominal cavity is influenced, and the operation is necessarily influenced; if the sheath moves outwards, once the front end of the sheath moves to the muscle layer, the channel is lost, the instrument cannot smoothly reach the abdominal cavity, and the puncture needs to be re-performed again, and the tissue is inevitably damaged again. To prevent the sheath from moving outwards, currently, there is only one way for the clinician to suture the skin with a triangular needle with a thread on the body surface, and then bind the thread to the thread structure (or step) of the sheath to prevent the sheath from moving outwards. However, the sheath cannot be blocked from moving into the abdominal cavity at present, once the sheath moves into the abdominal cavity, a clinician only has one way, namely an operation assistant, to pull the sheath outwards to a proper position by hand, so that the operation is facilitated.
3. Scolopendra scars form, which affects the appearance. With the improvement of living standard, people pay more and more attention to the attractive appearance of the postoperative scars, especially the visual impact of centipede scars when young people expose the abdomen on beach or wearing fashion clothing, and patients often feel very low. Since it is mentioned in the above 2, a triangle needle with a thread is needed to suture the skin in order to prevent the sheath from moving outwards. The triangular needle is used for needle insertion and needle extraction on the skin, and the wound presents triangular irregular patterns, so that scar healing (namely a dot) can occur in all needle eyes, and a post-operation puncture can be performed by adopting intradermal suture, and a line of postoperative scar is formed, so that centipede shape is formed.

The specific operation method of the adjustable bidirectional elastic fixation abdominal cavity puncture device of the embodiment is as follows:
1. A small opening (similar to the outer diameter of the sheath) was made in the skin at the surgical site with a blade, and then the sheath (with the core inserted into the sheath) was inserted into the abdominal cavity in a rotating manner until the balloon at the tip of the sheath completely entered the abdominal cavity.
2. And (3) injecting a small amount of gas or sterile normal saline into the balloon air inlet outside the sheath until the balloon at the front end of the sheath bulges, then stopping injecting the gas (or normal saline), and slightly pulling the tail of the sheath outwards until the balloon abuts against the abdominal wall.
3. Adjusting the fixation device outside the sheath, when the support rod of the sheath fixation device is close to the skin, the fixation device is fixed, the sheath core is pulled out, and the surgical instrument can be inserted. (because the supporting rods of the saccule and the external fixing device are all of elastic design, the sheath is elastically fixed on the abdominal wall by the saccule and the external fixing device at the moment, and can not move forwards and backwards, and can only shake by 360 degrees, thereby facilitating the operation).
4. After the operation, the balloon is firstly pumped back to the gas (or normal saline) until the balloon is completely retracted.
5. The sheath can be completely withdrawn by slightly pulling out the sheath, and the incision is sutured, so that the operation can be completed.
While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and the scope of the utility model is defined by the appended claims.
