Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a lower lip traction and fixation device. Background Art
[0002] When performing an operation on the inner membrane of a patient's lower lip, in order to solve the problems that it is easy to cause infection and unable to maintain the pulling force of the lower lip when the lower lip is pulled by an assistant, usually after the surgical assistant wears sterile gloves, the patient's lower lip is turned outwards to expose the surgical field. However, in this process, on the one hand, it is easy to cause cross-infection. On the other hand, the surgical assistant cannot maintain the same force for a long time. When the surgical assistant suddenly slips when pulling the lower lip, or fails to control the force of pulling the patient's lower lip, it is very likely to affect the doctor's operation. To solve the above problems, a lower lip traction device has emerged.
[0003] The existing lower lip traction device requires the patient to first put on a net cap on the head and place a neck support pad on the neck, and then by adjusting the length of the elastic band fixed to the net cap, clamp the lower lip and pull it down and turn it outwards, so as to facilitate the operation of medical staff. However, the following problems will exist in this process:
[0004] 1. Turning out the lower lip to expose the inside of the lower lip will cause the exposed surface of the lower lip to be parallel to the patient's face, and when the patient is sitting during the operation, when the medical staff performs an operation on the inside of the patient's lower lip, the wrist needs to be turned to a state perpendicular to the arm to perform the operation on the inner membrane of the lower lip. Long-term operation will cause the surgical staff's wrist to ache, fatigue or even become stiff, increasing the operation risk of the operation;
[0005] 2. During the patient's operation, on the one hand, there will be saliva in the oral cavity, and on the other hand, the lower lip glands will produce mucus. When the saliva and mucus flow to the operation area, on the one hand, it will affect the doctor's observation of the wound, and on the other hand, the bacteria remaining in the saliva and mucus may cause infection of the wound, thereby reducing the safety of the operation. Content of the Utility Model
[0006] In order to solve the above problems, the purpose of the utility model is to provide a lower lip traction and fixation device, in which the inner mucosa of the lower lip is perpendicular to the patient's face when being clamped, so as to avoid the ache, fatigue or even stiffness caused by the surgical staff's wrist turning to a state perpendicular to the arm during the operation, thereby reducing the risk caused by the problems of the surgical staff's hands.
[0007] To achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A lower lip traction and fixation device includes a clamping assembly disposed outside the patient's oral cavity for clamping the patient's lower lip and a limiting assembly disposed inside the patient's oral cavity and fixed to one side of the clamping assembly; the clamping assembly includes a pair of clamping plates hinged to each other and a V-shaped elastic member fixed between the front ends of the two clamping plates; through holes are formed in the middle parts of the two clamping plates in the thickness direction; the limiting assembly includes a limiting plate fixed to one side of the upper clamping plate and abutted against the patient's front teeth, and a pair of elastic limiting strips symmetrically disposed on both sides of the inner side of the limiting plate and abutted against the patient's rear teeth.
[0009] Preferably, first water-absorbing pads are fixed to the opposite sides of the two clamping plates.
[0010] Preferably, a second water-absorbing pad is fixed to the side of the limiting plate abutting against the front teeth, and water-absorbing sleeves are sleeved on the outer sides of the two elastic limiting strips.
[0011] Preferably, a secondary positioning plate abutting against the patient's chin is fixedly connected to the rear end below the lower clamping plate.
[0012] Preferably, the upper clamping plate and the limiting plate are integrally connected.
[0013] The utility model has the following beneficial effects:
[0014] 1. By clamping the lower lip with the two clamping plates, on the one hand, the inner mucosa of the lower lip can be fully exposed, improving the doctor's vision during the operation, thereby reducing the difficulty of the operation. On the other hand, under the limitation of the limiting assembly, when the clamping plates clamp the patient's lower lip, the inner mucosa of the lower lip is perpendicular to the patient's face. When the patient is sitting, the operator does not need to turn the wrist to a state perpendicular to the arm during the operation, thus avoiding the pain, fatigue or even stiffness caused by turning the wrist for a long time, and reducing the risk of the operation.
[0015] 2. The utility model can absorb the mucus generated by the lower lip glands during clamping through the first water-absorbing pad, and can absorb the saliva in the patient's oral cavity through the second water-absorbing pad and the water-absorbing sleeves, thereby avoiding the residue of mucus and saliva on the inner mucosa of the lower lip from affecting the doctor's observation of the wound, and also avoiding the infection of the wound by bacteria in the mucus and saliva, thus improving the safety of the operation.

[0020] The following further elaborates on the present utility model in detail with reference to the attached drawings and specific embodiments.
[0021] A lower lip traction and fixation device includes a clamping assembly 1 provided outside the patient's oral cavity for clamping the patient's lower lip and a limiting assembly 2 provided inside the patient's oral cavity and fixed to one side of the clamping assembly 1; the clamping assembly 1 includes a pair of clamping plates 11 hinged to each other and a V-shaped elastic member 12 fixedly arranged between the front ends of the two clamping plates 11; operation windows 111 are respectively formed through the middle parts of the two clamping plates 11 along the thickness direction; the limiting assembly 2 includes a limiting plate 21 fixedly connected to the clamping plate 11 located above and abutted against the patient's front teeth, and a pair of elastic limiting strips 22 symmetrically arranged on both sides of the inner side surface of the limiting plate 21 and abutted against the patient's rear teeth.
[0022] By abutting the two elastic limiting strips 22 and the limiting plate 21 against the patient's teeth, the limiting assembly 2 can be limited, preventing the clamping assembly 1 fixed to the limiting assembly 2 from moving during the operation, thus avoiding pulling on the lower lip during the operation and reducing the surgical risk; by clamping the lower lip with the two clamping plates 11, on the one hand, the inner mucosa of the lower lip can be fully exposed, improving the doctor's vision during the operation and reducing the difficulty of surgical operation, and on the other hand, under the limitation of the limiting assembly 2, when the clamping plates 11 clamp the patient's lower lip, the inner mucosa of the lower lip is perpendicular to the patient's face. When the patient is in a sitting position, the surgical staff does not need to turn the wrist to a state perpendicular to the arm during the operation, thus avoiding the pain, fatigue or even stiffness caused by long-term wrist turning, and reducing the surgical risk.
[0023] As a possible implementation mode of this solution, preferably, first water-absorbing pads 112 are respectively fixed on the opposite sides of the two clamping plates 11; the first water-absorbing pads 112 can absorb the mucus generated by the lower lip glands during clamping, thus preventing mucus from remaining on the inner mucosa of the lower lip and affecting the doctor's observation of the wound, and also preventing bacteria in the mucus from infecting the wound, thereby improving the safety of the operation.
[0024] As a possible implementation of this solution, preferably, a second water-absorbing pad 211 is fixed on the surface of the limiting plate 21 that abuts against the front teeth, and water-absorbing sleeves 221 are sleeved on the outer sides of the two elastic limiting strips 22; the second water-absorbing pad 211 and the water-absorbing sleeves 221 can absorb the saliva in the patient's oral cavity, so as to avoid the saliva flowing to the surgical area and affecting the doctor's observation of the wound, and at the same time avoid the bacteria in the saliva infecting the wound, thereby improving the safety of the operation.
[0025] As a possible implementation of this solution, preferably, an auxiliary positioning plate 13 that abuts against the patient's chin is integrally fixed at the rear end below the lower clamping plate 11; through the arrangement of the auxiliary positioning plate 13, the stability of the device during the clamping of the lower lip can be increased.
[0026] As a possible implementation of this solution, preferably, the upper clamping plate 11 and the limiting plate 21 are integrally connected; through the integral connection between the upper clamping plate 11 and the limiting plate 21, bacteria can be prevented from breeding in the gap between the two, thereby reducing the risk of wound infection during the operation.
[0027] The working principle of this device is as follows:
[0028] During use, the tails of the two elastic limiting strips 22 are respectively inserted into the gaps between the two sides of the teeth and the inner mucosa of the oral cavity, and then pushed into the patient's oral cavity until the limiting plate 21 abuts against the patient's front teeth. At this time, due to the elastic effect, the two elastic limiting strips 22 abut against the patient's teeth on both sides. Then, the two clamping plates 11 are pressed inward, so that the lower clamping plate 11 rotates downward, and the patient's lower lip is pulled to the wound in the operation window 111 and then the pressing on the two clamping plates 11 is released. At this time, under the action of the elastic member 12, the lower clamping plate 11 rotates upward, so as to cooperate with the upper clamping plate 11 to clamp the patient's lower lip. At this time, the auxiliary positioning plate 13 abuts against the patient's chin; in this device, in order to make the limiting component 2 better fit the patient's teeth, thereby increasing the stability of the device, both the limiting plate 21 and the elastic limiting strips 22 have a certain arc; in order to fully expose the surgical field of view and meet ergonomics at the same time, both clamping plates 11 have a certain arc, and the front part of the pressing end of the two clamping plates 11 is lower than the tail of the clamping end.
[0029] The above is only the specific implementation manner of the present invention, and does not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
