Description

Lateral bending right angle forceps

Technical field

This utility model relates to medical surgical instrument technical field.

Background technology

Due to the progress of technology, making to implement operation by less otch becomes possibility.Endoscope-assistant surgery be namely surgeon by inserting tiny light source from minimal incision *, monitor image that camera transmissions goes out guides and operates and implement operation, this new technique is less than traditional surgical operation to disorganization.What apply in current clinical operation is common right angle forceps, comprise two binding clips, two clamp handles and finger ring, binding clip is perpendicular to clamp handle place plane and be arranged on clamp handle front end, hinge is provided with in the middle part of the clamp handle of two decussations, finger ring is arranged on clamp handle end and finger ring clamp handle and finger ring are in same plane, the side that two finger rings are relative is provided with lock tooth, can carry out locking positioning to the right angle forceps of the state of cramping, easy to use.But along with the development of less invasive techniques, operative incision is more and more less, common right angle forceps is applied and is restricted in Minimally Invasive Surgery.When carrying out endoscope-assistant surgery, sometimes some minimal incision * needs to put in 2 ~ 3 simultaneously apparatus is performed the operation, and operation is influenced each other, cannot smooth operation.And, the right-angle structure of the binding clip part of common right angle forceps is owing to be in a plane with the vice body of clamp handle and perpendicular to clamp handle, overlook binding clip and clamp handle often distinguishes unclear, more not easily see clearly under the mirror of chamber, so can only lean at separating blood vessel with when organizing operator feel operate, be therefore easy to occur the risk that angiorrhexis or misoperation are brought.

Utility model content

Technical problem to be solved in the utility model is to provide simple, the easy to operate lateral bending right angle forceps of a kind of structure, makes operation technique more smooth, improves operation technique safety coefficient, be particularly useful for Minimally Invasive Surgery operation.

For solving the problems of the technologies described above, technical solution adopted in the utility model is:

A kind of lateral bending right angle forceps, comprise two binding clips, the clamp handle of two decussations and two finger rings, described two binding clips are arranged on two clamp handle front ends and upwards perpendicular to place, clamp handle front end plane, hinge is provided with in the middle part of described two clamp handles, described two finger rings are arranged on two clamp handle rear ends, clamp handle part between described hinge and finger ring is provided with opposing first bending downward in binding clip, makes finger ring place plane and place, clamp handle front end plane be α angle.

Preferably, the clamp handle end in described hinge front is provided with the second bending to the right, makes clamp handle front end have the bending at β angle.

Preferably, described α angle and β angle are 150 °.

Preferably, the first bending of described clamp handle is 15cm to the distance of finger ring link, and the first bending of described clamp handle and the distance of the second bending are 8cm, and the second bending of described clamp handle and the distance of binding clip are 3cm, and the height of described binding clip is 2cm.

Adopt the beneficial effect that produces of technique scheme to be: by by clamp handle postmedian to the first bending having α angle, avoid the finger ring impact operation visual field, rear portion, also the most advanced and sophisticated position of binding clip can be observed when the second bending that clamp handle front portion is provided with β angle to the right can make chamber mirror sight line parallel with clamp handle front portion vice body, make surgical field of view broader, more clear during operation technique, safer, realization can put in many apparatus simultaneously when carrying out small incision surgery, operation technique can be completed smoothly, can not interfere with each other.This utility model has simple, the easy to operate advantage of structure, makes operation technique more smooth, improves operation technique safety coefficient, be particularly useful for endoscope-assistant surgery operation.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.

A kind of lateral bending right angle forceps as shown in Fig. 3,4,5, comprise clamp handle 2 and the finger ring 3 of two binding clips, 1, two decussations, described two binding clips 1 are arranged on two clamp handle 2 front ends and upwards perpendicular to place, clamp handle 2 front end plane, hinge 4 is provided with in the middle part of described two clamp handles 2, described two finger rings 3 are arranged on two clamp handle 2 rear ends, clamp handle 2 part between described hinge 4 and finger ring 3 is provided with opposing first bending 5 downward in binding clip 1, makes finger ring 3 place plane and place, clamp handle 2 front end plane be α angle.Clamp handle 2 end in described hinge 4 front is provided with the second bending 6 to the right, makes clamp handle 2 front end have the bending at β angle.Described α angle and β angle are 150 °.

Conveniently in Minimally Invasive Surgery compared with the operation of position, deep, the distance of the first bending 5 to finger ring 3 link of described clamp handle 2 is 15cm, first bending 5 of described clamp handle 2 and the distance of the second bending 6 are 8cm, second bending 6 of described clamp handle 2 is 3cm with the distance of binding clip 1, and the height of described binding clip 1 is 2cm.

By by clamp handle 2 postmedian to the first bending 5 having α angle, avoid rear portion finger ring 3 to occur at minimal incision * place and other apparatuses mutually to disturb, realization can put in many apparatus simultaneously when carrying out small incision surgery, operation technique can be completed smoothly, clamp handle 2 front portion is provided with second bending 6 at β angle to the right, the most advanced and sophisticated position also can observing binding clip 1 when chamber mirror sight line is parallel with the anterior vice body of clamp handle 2 can be made, make surgical field of view broader, more clear during operation technique, safer.This utility model has the advantage that structure is simple, easy to operate, cost of manufacture is low, makes operation technique more smooth, improves operation technique safety coefficient, be particularly useful for Minimally Invasive Surgery operation.
