Description
Technical field
This utility model belongs to surgical instruments field, relates to a kind of operation pliers, is specifically related to a kind of Minimally Invasive Surgery pincers.
Background technology
Minimally Invasive Surgery refers to the operation that modern medical equipment such as utilizing various endoscopies and relevant auxiliary facilities are carried out.The operating theater instruments of Minimally Invasive Surgery is entered in human body by operating walk way, so operating theater instruments is relatively little, high to the requirement of operating forceps.
Pincers are apparatuses of a kind of similar tweezers, rely on the mechanism between its clamp to capture, clamp and compress blood vessel or tissue.In general, operating theater instruments (comprising pincers) can be classified as disposable using apparatus, the reusable apparatus of part and overall reusable apparatus.As may be appreciated, can be sterilized and the apparatus be reused (or device element) helps to reduce the relevant cost of concrete surgical operation used.But, although reusable operating theater instruments is controlled cost effectively, but importantly these apparatuses can play identical effect with its disposable counterpart, and any disposable unit of these apparatuses can be removed efficiently and be substituted by new parts.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and this utility model provides one can change clamp, easy to operate Minimally Invasive Surgery pincers.
Basis is practical to be newly achieved through the following technical solutions:
Minimally Invasive Surgery clamps, comprise caliper, fixed handle and flexible handle, fixed handle is fixed on the rear end of caliper, flexible handle is arranged on the front end of caliper by bearing pin-I, spring is provided with between flexible handle and fixed handle, caliper hollow and surface has chute, the square aperture being provided with one above of caliper, slide is provided with in chute, connected with link rotatable by rotating shaft above slide, the connecting rod other end is connected with flexible handle by bearing pin-II through square aperture, stock is installed in slide side, clamp is installed in stock front end, clamp comprises clamp connection seat, upper clamp, lower clamp and little spring three part, little spring is arranged between clamp and lower clamp, upper clamp and lower clamp are fixedly connected on clamp connection seat by rotating shaft, stock overcoat has sleeve pipe, sleeve pipe is fixed on caliper, the internal diameter of sleeve pipe matches with the external diameter of clamp connection seat.
Clamp connection seat is connected by screw thread or draw-in groove with stock, conveniently replaces clamp.
When this utility model uses, first clamp is arranged on stock, flexible handle under the action of the spring, be in releasing orientation, move after driving stock, make in clamp afterbody indentation sleeve pipe, upper clamp and lower clamp close, flexible handle of holding with a firm grip, and stock moves forward, clamp is made to stretch out sleeve pipe, upper clamp and lower clamp are opened, and this device mobile, moves to active position by clamp, then unclamp flexible handle, upper clamp and lower clamp close.
Compared with prior art, this utility model has following beneficial effect:
This utility model clamp can be changed, and structure is simple, uses, easily manufactured.
Accompanying drawing explanation
Labelling in the content expressed each width accompanying drawing of this utility model description below and figure is briefly described:
Fig. 1 is structural representation of the present utility model;
In figure: 1, lower clamp, 2, little spring, 3, upper clamp, 4, clamp, 5, clamp connection seat, 6, sleeve pipe, 7, bearing pin-I, 8, bearing pin-II, 9, connecting rod, 10, stock, 11, slide, 12, chute, 13, caliper, 14, fixed handle, 15, spring, 16, flexible handle.
Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, detailed description of the invention of the present utility model is described in further detail.
Minimally Invasive Surgery pincers as shown in Figure 1, comprise caliper 13, fixed handle 14 and flexible handle 16, fixed handle 14 is fixed on the rear end of caliper 13, flexible handle 16 is arranged on the front end of caliper 13 by bearing pin-I7, spring 15 is provided with between flexible handle 16 and fixed handle 14, caliper 13 hollow and surface has chute 12, the square aperture being provided with one above of caliper 13, slide 11 is provided with in chute 12, to be rotated with connecting rod 9 by rotating shaft above slide 11 and connect, connecting rod 9 other end is connected with flexible handle 16 by bearing pin-II8 through square aperture, stock 10 is installed in slide 11 side, clamp 4 is installed in stock 10 front end, clamp 4 comprises clamp connection seat 5, upper clamp 3, lower clamp 1 and little spring 2 three part, little spring 2 is arranged between clamp 3 and lower clamp 1, upper clamp 3 and lower clamp 1 are fixedly connected on clamp connection seat 5 by rotating shaft, stock 10 overcoat has sleeve pipe 6, sleeve pipe 6 is fixed on caliper 13, the internal diameter of sleeve pipe 6 matches with the external diameter of clamp connection seat 5.
