Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments and in particular to a pair of micro forceps for oral surgery. Background Art
[0002] In many oral implant surgeries, bone augmentation (bone grafting) surgery is required due to insufficient bone volume at the edentulous site. The last step of this type of surgery usually requires the soft tissue flap to be tension-relieved before the wound can be closed without tension. This step is one of the key steps in bone grafting surgery. It is necessary to protect the soft tissue flap from damage while being as minimally invasive as possible. At the same time, it is necessary to ensure that the deep surface of the flap tissue is clearly exposed and maintains a certain tension to facilitate sharp separation of the periosteum by instruments such as scalpels. In clinical practice, tissue forceps are usually used to clamp the edge of the soft tissue flap and pull the exposed tissue surface. The beak end of the tissue forceps currently used in clinical practice is narrow, and the exposure range of the clamped and pulled tissue flap is limited. The intraoperative field of view is not clear enough, which affects the accuracy of surgical operations and work efficiency.
[0003] Therefore, in order to solve the deficiencies in the prior art, a microscopic forceps for oral surgery with a simple structure needs to be designed. Utility Model Content
[0004] The utility model provides a pair of micro forceps for oral surgery to solve the problems of the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions: A micro-tweezers for oral surgery comprises: a micro-tweezers main body and a pushing device, the micro-tweezers main body comprises a female piece and a male piece, the female piece is sleeved and fixed on the left end of the male piece, a slide groove is provided inside the female piece, and the top of the slide groove is through-set, the pushing device comprises a pushing wrench, a spring pushing block, a spring, a push rod and a supporting block, the push rod is slidably arranged in the slide groove, the support block is fixed to the left end of the push rod and is located outside the female piece, the spring is sleeved on the push rod and is located inside the slide groove, the spring pushing block is fixed to the right end of the push rod and is located on the right side of the spring, the pushing wrench is rotatably connected to the upper end of the spring pushing block, and the upper end surface on the left side of the female piece is provided with a card slot for matching the pushing wrench.
[0006] As a further improvement, the support block has an arc cross section.
[0007] As a further improvement, a groove is provided on the male piece.
[0008] As a further improvement, the pushing device also includes a cover plate, which is arranged inside the slide groove and located at the lower side of the spring.
[0009] Compared with the prior art, the utility model of the micro forceps for oral surgery has the following beneficial effects:
[0010] The driving push wrench drives the spring push block to move the push rod, compressing the spring, thereby causing the support block connecting the push rod to move to the left and extend out. After the push wrench moves to the specified position, it is rotated and inserted into the slot and fixed. Through the extended support block and push rod, the head end size of the left end of the female piece is widened, with a larger contact area, easier to flip, and a larger exposure range of the surgical area. It has the functions of pulling, maintaining the tension of the soft tissue flap, reducing soft tissue clamping damage, and protecting important anatomical structures such as nerves and blood vessels, which is beneficial to surgical operations.

[0015] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0017] Below is a combination of the embodiments and the attached Figures 1 to 3 , the technical solution of the utility model is further elaborated.
[0018] Example 1
[0019] A micro-tweezers for oral surgery comprises: a micro-tweezers main body 1 and a pushing device 2, wherein the micro-tweezers main body 1 comprises a female piece 3 and a male piece 4, wherein the female piece 3 is sleeved and fixed on the left end of the male piece 4, a slide groove 31 is provided inside the female piece 3, and the top of the slide groove 31 is provided through, the pushing device 2 comprises a pushing wrench 21, a spring pushing block 22, a spring 23, a push rod 24 and a supporting block 25, wherein the push rod 24 is slidably arranged in the slide groove 31, the supporting block 25 is fixed to the left end of the push rod 24 and is located outside the female piece 3, the spring 23 is sleeved on the push rod 24 and is located inside the slide groove 31, the spring pushing block 22 is fixed to the right end of the push rod 24 and is located on the right side of the spring 23, the pushing wrench 21 is rotatably connected to the upper end of the spring pushing block 22, and a card slot 32 matching the pushing wrench 21 is provided on the upper end surface of the left side of the female piece 3.
[0020] As shown in the figure, the use principle of the utility model is as follows: the main body 1 of the microscopic forceps still has the clamping function of conventional forceps. In the normal use state, the push wrench 21 is located on the right side of the slide groove 31 of the female piece 3, and the support block 25 is away from the left head end of the female piece 1; when a larger exposure range is required under special circumstances, the push wrench 21 is driven to drive the spring push block 22 to move the push rod 24, compress the spring 23, and then the support block 25 is connected to the push rod 24 and moves out to the left.
