A kind of not damaged clamp of Minimally Invasive Surgery nipperTechnical field
The utility model is related to a kind of not damaged clamp of Minimally Invasive Surgery nipper, and mainly carrying out separation to people's in-vivo tissue grabsMovement is taken, belongs to technical field of medical instruments.
Background technology
Minimally Invasive Surgery is video operation, and application apparatus completely is operated in operation, so being needed in operationMany using apparatus species, Technology design of the present utility model is separated applied to people's in-vivo tissue, captured, mobile nipperNot damaged clamp.Prior art is using common pincers class, such as elastic separating plier, nipper；In operation application, elastic separating plier clamp is short to grabEasily slipped in taking, the sharp rapid wear injured tissue in crawl of nipper clamp clip tooth can not meet preferable surgical effect.
Utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency in the presence of prior art, and provides oneIt is kind reasonable in design, be difficult to slip during gripping, and will not injury tissue organ Minimally Invasive Surgery nipper not damaged clamp.
The utility model solves the technical scheme that is used of above-mentioned technical problem：A kind of not damaged of Minimally Invasive Surgery nipperClamp, including two jaw arms, the end of two jaw arms are interconnected, it is characterised in that：Described jaw arm includes mutualThe clip tooth matched each other is provided with the inside of the binding clip and clamping limb of connection, two binding clips, the inner side of two clamping limbs is provided withNeck, the size and location of neck is mutually symmetrical with.During operation, clamp clamps in-vivo tissue organ, and clip tooth clamps histoorgan,During clamping, portion of tissue is caught in neck, will not be moved, and is clamped more firm, it is ensured that operation is smoothed out.
The top of clip tooth described in the utility model is circular arc.The clip tooth of circular arc will not injury tissue while clampingOrgan.
Neck described in the utility model is strip, and neck extends to the clip tooth position of binding clip from clamping limb.Neck is matched somebody with somebodyThe clip tooth of circular arc is closed, is caught in while being organized in clamping in neck, will not be moved and come off.
The end of two jaw arms described in the utility model makes clamp gripping more flexible by fixed pin connection.
The top of binding clip described in the utility model is circular arc.When binding clip is closed, top is in integrally arc-shaped, is grasped in vivoHistoorgan will not be scratched when making.
The end of two jaw arms described in the utility model is provided with the attachment structure being connected with Minimally Invasive Surgery nipper, connectionStructure is used for the caliper that two jaw arms are arranged on to surgical grasping forceps.
The utility model compared with prior art, with following positive effect：Reasonable in design, to organizer during operationThe clamping effect of official is good, it is ensured that operation is smoothed out.

Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by embodiment.
Embodiment：
Referring to Fig. 1~Fig. 2, the present embodiment includes two jaw arms 1, and the end of two jaw arms 1 is interconnected, describedJaw arm 1 includes the binding clip 11 and clamping limb 12 interconnected, and the inner side of two binding clips 11 is provided with the clip tooth 2 matched each other,The inner side of two clamping limbs 12 is provided with neck 3, and the size and location of neck 3 is mutually symmetrical with.During operation, group in clamp clamping bodyOrgan is knitted, clip tooth 2 clamps histoorgan, during clamping, portion of tissue is caught in neck 3, will not moved, clamping is more firm,Ensure that operation is smoothed out.
In the present embodiment, the top of clip tooth 2 is circular arc.The clip tooth 2 of circular arc will not injury tissue while clampingOrgan.
In the present embodiment, neck 3 is strip, and neck 3 extends to the position of clip tooth 2 of binding clip 11 from clamping limb 12.Neck 3The clip tooth 2 of fit circular arc shape, is caught in while being organized in clamping in neck 3, will not move and come off.
In the present embodiment, the end of two jaw arms 1 is connected by steady pin 4, makes clamp gripping more flexible.
In the present embodiment, the top of binding clip 11 is circular arc.When binding clip 11 is closed, top is in integrally arc-shaped, in vivoHistoorgan will not be scratched during operation.
In the present embodiment, the end of two jaw arms 1 is provided with the attachment structure 5 being connected with Minimally Invasive Surgery nipper, connectionStructure 5 is used for the caliper that two jaw arms are arranged on to surgical grasping forceps.In the present embodiment, attachment structure 5 is connecting screw hole.
In use, the utility model is arranged on Minimally Invasive Surgery nipper, pass through opening for nipper two jaw arms 1 of controlClose.The design of circular arc clip tooth 2 causes clamp to clamp crawl people's in-vivo tissue, when moving separation, can never damage groupKnit；Tissue is caught in neck 3 while clamping, is clamped more firm, it is ensured that what operation was applied is smoothed out.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, as long as its part does not specify specific shapeShape and size, then the part can be any shape and size being adapted with its structure；Meanwhile, the title that part is takenCan be different.The equivalent or simple change that all construction, feature and principles according to described in the utility model inventional idea are done, is wrappedInclude in the protection domain of the utility model patent.
