Description

A microvascular clip holder

technical field

The utility model belongs to the field of medical instruments, and relates to a medical instrument for microsurgery, in particular to a blood vessel clip holder.

Background technique

At present, microsurgery technology has become a basic surgical method, and plays an irreplaceable role in the replantation of severed limbs and free tissue transplantation of tissue and organ defects. Microvascular clips are commonly used instruments in the implementation of microsurgery techniques. . However, its small size makes it inconvenient to take and place it. When placing the vascular clamp by hand, the movement is not fine enough, and the hand strength is uneven. The smaller the volume, the greater the hand strength required to open it, and the hand is easy to feel Fatigue may even cause pain; when the surgical incision is relatively small, the hand will block the view, which will restrict the placement of the vascular clip and cause certain difficulties for the operation; in addition, the occlusal surface of the vascular clip is closed, and the inner texture is dry. The blood scab is not easy to clean, and the enzyme in the ultrasonic cleaning machine is not easy to contact with the occlusal surface, teeth, grooves and other dead corners. The cleaning quality will directly affect the sterilization effect of the instrument, and there is a potential risk of infection in subsequent use.

Chinese Patent No. CN201020503655.8 Utility Model Patent Specification discloses a blood vessel clamping forceps, including a handle, a jaw and a handle. The jaws are provided with an upper groove and a lower groove, and the raised part of the blood vessel clamp is placed on the In the groove of the jaws, the opening and closing of the jaws is controlled by the handle. Although the clamping forceps can effectively control the opening or closing of the blood vessel clamp, because the clamp handle, the jaws and the handle are in a straight line, the clamping forceps cannot be clamped during use. The pliers will definitely affect the operator's field of vision; in addition, if the clamping pliers is required to provide continuous and stable force, such as cleaning the vascular clamp, the operator must always hold the handle firmly, which will cause inconvenience to the operation and affect work efficiency.

Utility model content

Aiming at the deficiencies of the above-mentioned technologies, the utility model provides a microvascular clip holder, which can provide a uniform, continuous and stable force, can reduce the work intensity of the operator, improve the operation efficiency, improve the cleaning quality, and prevent The occurrence of nosocomial infection plays an important role.

The purpose of this utility model is achieved in the following way: a microvascular clip holder, including a clamp handle, a curved handle, a clamp head and a self-locking device, the two inner surfaces of the clamp head are respectively provided with grooves; its characteristics In that: the pliers handle is connected to the pliers head through an angled curved handle, and a self-locking device is arranged inside the curved handle, and the self-locking device is arranged at a bend inside the curved handle.

The self-locking device is composed of a reed and a hole, and the bottom surface of the reed and the bottom of the hole are both provided with non-return teeth that can engage with each other.

The protruding part of the blood vessel clip fits in the groove, and the bottom surface of the groove is provided with anti-slip lines.

Anti-slip lines are provided on the outside of the pliers handle.

The bending angle of the bending handle is 120°.

The utility model has the advantages of simple structure, easy manufacture, accurate positioning during use, labor saving, not easy to slip off, can fully expose the surgical field of view, reduces the operation difficulty of the operation, and ensures the normal operation of the operation; in addition, the clamper has a self-locking device, The use of this holder can provide uniform, continuous and stable force to the vascular clip, facilitate the cleaning of the occlusal surface, teeth, and dead corners of the vascular clip, provide a strong guarantee for the sterilization of the instrument, and eliminate potential risks during the operation. risks of.

In the figure: pliers handle 1, curved handle 2, pliers head 3, groove 4, self-locking device 5, vascular clamp protrusion 6.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figure 1-2, a microvascular clamp holder includes a clamp handle 1, a curved handle 2, a clamp head 3 and a self-locking device 5. It is a pliers-like structure as a whole, and grooves 4 are respectively arranged on the two inner surfaces of the forceps head 3. The grooves are rectangular grooves, and the grooves 4 are clamped on the raised part 6 of the blood vessel clip. The anti-slip texture of the clip slides. The pliers handle 1 is connected to the pliers head 3 through the curved handle 2. The outer side of the pliers handle 1 has anti-slip textures to prevent the hand from slipping off. The bending angle of the curved handle is 120°. The locking device 5 and the self-locking device 5 are composed of reeds and slots. The reeds and slots are respectively arranged at the inner bends of the two curved handles. The bottom surface of the reeds and the bottom surface of the slots are provided with non-reversing teeth that can mesh with each other.

As shown in Figure 1-2, when in use, place the protruding part 6 of the blood vessel clip in the normally closed state in the groove 4 of the clamp head, hold the handle of the clamp, and make the clamp head slowly Entering the closure, during the closing process, the protruding part 6 of the blood vessel clip will be pressed, and the chuck part of the blood vessel clip will be stretched. At the same time, the spring in the self-locking device and the backstop teeth in the hole Engaging and locking are performed to lock the working state of the clamp head 1, and the chuck part of the blood vessel clamp is also in a normally open state, which is not only convenient for the operator to quickly and accurately locate, but also facilitates postoperative disinfection and cleaning. Conversely, if the clamp head of the blood vessel clip needs to be closed, it is only necessary to lift up the reed in the self-locking device to loosen the mutual engagement, and the clamp head of the blood vessel clip will close by itself.
