Description

A kind of Minimally Invasive Surgery vascular occlusion clamp

Technical field

This utility model relates to a kind of Minimally Invasive Surgery vascular occlusion clamp, belongs to technical field of medical instruments.

Background technology

In recent years, minimally-invasive treatment has become a kind of trend of operative treatment, and laparoscopic technique is a kind of as the Minimally Invasive Surgery treatment, is widely used in clinical especially.Laparoscopic technique helps patient's postoperative rehabilitation, save medical expense, but peritoneoscope is than traditional operation specification requirement height, in the laparoscopic surgery if cause trunk damage because of reasons such as blood vessel variation, adhesion, surgical technic careless manipulations, bleed profusely and cause, Minimally Invasive Surgery medium vessels blocking-up for want of and the operating theater instruments of sewing up, have to interrupt Minimally Invasive Surgery, and carry out the vascular suture art with open surgery, this brings adverse influence can for patient's post-operative recovery, also causes some medical tangles easily.

Summary of the invention

The purpose of this utility model provides a kind of Minimally Invasive Surgery vascular occlusion clamp, and it can carry out the stitching of blood vessel under peritoneoscope, avoids having to adopt open surgery to carry out the deficiency of vascular suture art because of the trunk damage in the Minimally Invasive Surgery.

In order to achieve the above object, this utility model provides a kind of Minimally Invasive Surgery vascular occlusion clamp, comprise first handle and second handle, it is characterized in that, the front end of first handle and second handle is connected, second handle connects the rear end of first clamp and second clamp respectively by linkage, and the outside of linkage is provided with cylindrical casing, and the middle part of the middle part of first clamp, second clamp and the front end of cylindrical casing interconnect.

Preferably, described linkage comprises pull bar, and an end of pull bar connects second handle by pin, and the other end of pull bar connects first connecting rod and second connecting rod respectively, and first connecting rod and second connecting rod are connected the rear end of first clamp and second clamp respectively.

Preferably, have two toothrows on described first clamp, have a toothrow on second clamp, when first clamp and second clamp closure, the toothrow on second clamp is positioned at the centre of two toothrows on first clamp.When two clamps are closed, form the engagement of groove and flange, can effectively block blood vessel and don't injured blood vessel.

Preferably, the front end of described first clamp and second clamp is all arc.Be convenient to the patient can finish damaged blood vessel under the mirror of chamber stitching.

Preferably, be provided with the clamp retaining mechanism between first handle and the second handle.

Preferably, described clamp retaining mechanism is made up of first Saw blade and second Saw blade, and first Saw blade links to each other with second handle with first handle respectively with second Saw blade, and the serrated portion of first Saw blade and second Saw blade is intermeshed.The clamp retaining mechanism is used to control the tightness of the switching and the blocking-up of clamp.

The utility model has the advantages that: can in endoscope-assistant surgery, carry out vascular suture, avoid damaging the problem of having to interrupt Minimally Invasive Surgery because of trunk.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 1, be Minimally Invasive Surgery vascular occlusion clamp structural representation, described Minimally Invasive Surgery is made up of first handle 1, second handle 2, clamp retaining mechanism 3, cylindrical casing 4, linkage 5, first clamp 6 and second clamp 11 with vascular occlusion clamp.The front end of first handle 1 and second handle 2 is connected at position d place, second handle 2 connects the rear end of first clamp 6 and second clamp 11 respectively by linkage 5, the outside of linkage 5 is provided with the middle part of cylindrical casing 4, the first clamps 6, the middle part of second clamp 11 and the front end of cylindrical casing 4 and interconnects at position a place.Linkage 5 is made up of pull bar 8, pin 9, first connecting rod 7 and second pull bar 10.One end of pull bar 8 connects second handles 2 by pin 9, and the other end of pull bar 8 connects first connecting rod 7 and second connecting rod 10 respectively, and first connecting rod 7 and second connecting rod 10 are connected the rear end of first clamp 6 and second clamp 11 respectively.Be provided with clamp retaining mechanism 3 between first handle 1 and the second handle 2.

As shown in Figure 4, be the clamp partial enlarged drawing, the front end of described first clamp 6 and second clamp 11 is all arc, is convenient to the patient can finish damaged blood vessel under the mirror of chamber stitching.Have two toothrows on first clamp 6, have a toothrow on second clamp 11, when first clamp 6 and second clamp, 11 closures, the toothrow on second clamp 11 is positioned at the centre of two toothrows on first clamp 6.When clamp is closed, form the engagement of groove and flange, can effectively block blood vessel and don't injured blood vessel.

As shown in Figure 5, be clamp locking device part enlarged drawing, described clamp retaining mechanism 3 is made up of first Saw blade 12 and second Saw blade 13, first Saw blade 12 links to each other with second handle 2 with first handle 1 respectively with second Saw blade 13, the serrated portion of first Saw blade 12 and second Saw blade 13 is intermeshed, with the switching of control clamp and the tightness of blocking-up.

Described Minimally Invasive Surgery is 200-500mm with the long L1 of vascular occlusion clamp.The arc length L2 of described first clamp 6 and second clamp 11 is all 20-70mm, and the height H of first clamp 6 and second clamp 11 is all less than 10 mm.

As shown in Figure 2, be the handle schematic diagram of movements of Minimally Invasive Surgery with vascular occlusion clamp, when clutching second handle 2, second handle 2 rotates around the d point, the angle α of 2 of first handle 1 and second handles is reduced, groove in the second handle 2 is moved to the left pull bar 8 by connecting pin 9, as shown in Figure 3, be the clamp schematic diagram of movements of Minimally Invasive Surgery with vascular occlusion clamp, when pull bar 8 is moved to the left, the angle β of 10 of first connecting rod 7 in the hinge means 5 and second connecting rods is reduced, drive first clamp 6 and second clamp 11 and rotate, thereby clamp is clamped around a point.
