Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a device for regionally intact extraction of the oral mucosa in surgery involving the excision of the oral mucosa to repair an exposed prosthetic eye or a superficial conjunctival sac. Background Technology

[0002] Clinically, patients often require enucleation or removal of eye contents due to intraocular malignant tumors, severe ocular trauma, or other reasons. During the surgery, an artificial eye implant may or may not be implanted depending on the specific condition, and a prosthetic eye is worn postoperatively to improve appearance. However, postoperative complications such as conjunctival wound dehiscence, exposure of the artificial eye implant, and infection are common due to inadequate postoperative care and infection. Furthermore, an ill-fitting prosthetic eye, or chemical burns or thermal injuries to the eye, can easily lead to conjunctival sac stenosis, making it impossible to fit the prosthetic eye properly.

[0003] For cases of exposed prosthetic eye sockets and conjunctival sac stenosis requiring surgical repair, currently used repair materials include oral mucosa, buccal mucosa, allogeneic acellular dermis, amniotic membrane, and cardiac capsule, which can be used alone or in combination. Among these, oral mucosa is the most commonly used repair material due to its autologous nature and ease of harvesting.

[0004] Currently, the traditional method of extracting oral mucosa involves medical staff manually using a blade to cut and extract the mucosa inside the patient's lower lip. This method is time-consuming and laborious, and the force and thickness of the cut require the medical staff to judge with extensive experience, which greatly increases the difficulty of the work. In view of the above shortcomings, it is necessary to design a device for regional complete extraction of oral mucosa. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device for regionally intact extraction of oral mucosa, so as to solve the problems raised in the background art.

[0007] Furthermore, the clamping mechanism consists of a handle, a guide sleeve, a clamping plate, and a first spring.

[0008] Furthermore, a guide sleeve is fixedly provided on the bottom right side of the handle, and a clamping plate is slidably provided inside the guide sleeve.

[0009] Further, the first spring is fixedly arranged on the top of the clamping plate.

[0010] Further, the driving mechanism is composed of a motor, a driving shaft, a driven shaft and a belt.

[0011] Further, the motor is fixedly arranged on the right side of the rear end of the rectangular frame, and the driving shaft is rotatably connected to the motor.

[0012] Further, the driven shaft is rotatably arranged on the left side of the rectangular frame, and the belt is tightly matched with the driven shaft and the driving shaft.

[0013] Further, the cutting mechanism is composed of a mounting pin, a sliding pin, a blade and a second spring.

[0014] Further, the mounting pin is fixedly arranged on the left side of the outer wall of the belt from front to back, and the sliding pin is slidably arranged in the mounting pin.

[0015] Further, the blade is fixedly arranged on the outer side of the sliding pin, the second spring is fixedly arranged on the inner side of the sliding pin, and the second spring is fixedly connected with the mounting pin.

[0016] Compared with the prior art, the oral mucosa regional complete extraction device can control the force and thickness of the oral mucosa removed from the patient's mouth to be within the requirements of medical personnel without manual operation of medical personnel, thereby reducing the difficulty of medical personnel in the oral mucosa cutting operation.

A clamping mechanism 2 for fixing the position of the patient's lower lip is fixed on the right side of the rectangular frame 1. A driving mechanism 3 is fixed inside the rectangular frame 1. A resection mechanism 4 for extracting the patient's lower lip mucosa is fixed on the outer wall of the driving mechanism 3. A lithium battery 5 is tightly fitted inside the clamping mechanism 2. A protective plate 6 is fixed on the top of the rectangular frame 1.

[0027] This device for the complete regional extraction of oral mucosa involves the following steps: First, medical personnel use the clamping mechanism 2 to hold the edge of the patient's lower lip, effectively pulling the lower lip open. Simultaneously, the rectangular frame 1 is positioned above the patient's lower lip mucosa. Then, the medical personnel activate the drive mechanism 3, which controls the cutting mechanism 4 to move from left to right across the patient's mucosa, thus removing and extracting the mucosa. Furthermore, the cutting mechanism 4 exerts a soft pressure on the patient's oral mucosa, allowing for control of the cutting force and depth.
