Description

Technical Field

[0001] This utility model relates to a maxillary sinus floor lifting tool, belonging to the field of medical device technology. Background Technology

[0002] Dental implants have become the dominant method for restoring missing teeth. However, after the loss of maxillary posterior teeth, there is often insufficient vertical alveolar bone. Maxillary sinus floor elevation through fenestration of the maxillary sinus lateral wall is one of the commonly used methods to solve the problem of severe bone deficiency in the maxillary posterior tooth region.

[0003] However, complications such as maxillary sinus mucosal dissection leading to maxillary sinus mucosal periosteum occur frequently during surgery. Currently, the commonly used tool for maxillary sinus mucosal dissection via the lateral wall of the maxillary sinus is a metal dissection tool. During the operation, the patient needs to cooperate with breathing. When the patient inhales, the maxillary sinus mucosa moves away from the maxillary sinus wall, which is conducive to the dissection of the maxillary sinus mucosa. However, it is not easy for the patient to cooperate with breathing during the operation, which makes the dissection of the maxillary sinus mucosa difficult and leads to the perforation of the maxillary sinus membrane. Therefore, there is an urgent need in this field for a maxillary sinus floor lifting tool that can assist in the dissection of the maxillary sinus mucosa and reduce the rate of mucosal perforation. Utility Model Content

[0004] The technical problem this invention aims to solve is how to better perform maxillary sinus mucosal dissection and reduce the mucosal perforation rate when patients with missing maxillary posterior teeth have difficulty cooperating with breathing.

[0005] To address the aforementioned technical problems, this utility model provides a maxillary sinus floor lifting tool that uses applied air pressure to move the dissected portion of the mucosa away from the maxillary sinus bone wall, thereby enabling maxillary sinus mucosal dissection and effectively preventing maxillary sinus membrane perforation during surgery.

[0006] To achieve the above-mentioned technical objectives and effects, this application provides the following technical solution:

[0007] A maxillary sinus floor lifting tool includes a handle and a dissector. The dissector includes a connector and a dissector head. The connector is detachably connected to the handle. The dissector head is located at one end of the connector opposite to the handle. The connector has a positive pressure airway one. The dissector head has a positive pressure airway two communicating with the positive pressure airway one on the side opposite to the connector. The handle contains a pump body with an air inlet communicating with the positive pressure airway one. The handle has a control switch for controlling the operation of the pump body.

[0008] Preferably, the pump body is a miniature pump that can be used for both pumping and air intake and has an air intake port. The connecting body is provided with a negative pressure air passage one, and the peeling head is provided with a negative pressure air passage two that communicates with the negative pressure air passage one. The pump body's air intake port is connected to the negative pressure air passage one.

[0009] Preferably, the peeling head includes, but is not limited to, a disc-shaped or elliptical peeling head.

[0010] Furthermore, the connector includes a connecting part and an operating part. One end of the connecting part is inserted into the handle, and the other end of the connecting part is bent upward to form the operating part. The peeling head is disposed at the end of the operating part away from the connecting part.

[0011] Furthermore, when the peeling head is disc-shaped, the connection point between the peeling head and the operating part is located at the center of the disc of the peeling head.

[0012] Furthermore, when the peeling head is elliptical, the connection point between the peeling head and the operating part is located at the right edge of the elliptical peeling head, that is, the peeling head and the connecting part are arranged in opposite directions.

[0013] Furthermore, when the peeling head is elliptical, the connection point between the peeling head and the operating part is located at the left edge of the elliptical peeling head, that is, the peeling head and the connecting part are arranged in the same direction.

[0014] Furthermore, the operating part and the connecting part are bent at 120° to 135°.

[0015] Furthermore, the operating part is arranged in a spiral shape with one spiral turn, and the peeling end of the peeling head is located inside the end of the operating part away from the connecting part.

[0016] Furthermore, a scale bar is provided on the outer wall of the operating part, the scale bar being located from the corner of the operating part and the connecting part to the end of the operating part away from the connecting part.

[0017] The maxillary sinus floor lifting tool provided by this utility model has the following advantages:

[0018] 1. The maxillary sinus floor lifting tool of this utility model does not require the patient's breathing cooperation. The pump body applies air pressure to the dissection head to move the dissected part of the mucosa away from the maxillary sinus bone wall, so as to facilitate the maxillary sinus lateral wall fenestration operation and effectively reduce the phenomenon of maxillary sinus membrane perforation.

[0019] 2. The maxillary sinus floor lifting tool of this utility model is designed as a miniature pump that can be used for both suction and inflation. It can facilitate the peeling of the maxillary sinus mucosa through positive pressure and can also aspirate blood and fluid from the surgical area through negative pressure, thus providing a clear field of vision.

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1:

[0030] Reference Figures 1-3 A maxillary sinus floor lifting tool, comprising a handle 1 and a dissector 2;

[0031] The dissector 2 includes a connector 21 and a dissector head 22. The connector 21 is detachably connected to the handle 1. The dissector head 22 is integrally formed on the end of the connector 21 opposite to the handle 1. A positive pressure airway 213 is provided on the connector 21. A second positive pressure airway 221 communicating with the first positive pressure airway 213 is provided on the side of the dissector head 22 opposite to the connector 21. A pump body 3 is installed inside the handle 1. The pump body 3 has an air inlet 31, which is connected to the first positive pressure airway 213. During the surgical procedure, the dissector head 22 is used to partially dissect the maxillary sinus mucosa. The maxillary sinus lateral wall is then inflated by the pump body 3 to generate positive pressure between the maxillary sinus and the maxillary sinus mucosa, so that the maxillary sinus mucosa is always away from the maxillary sinus lateral wall, which facilitates the maxillary sinus opening operation and reduces the probability of mucosal perforation. The handle 1 is equipped with a control switch 4 that is electrically connected to the pump body 3 and controls the operation of the pump body 3, so that medical staff can perform the inflation operation at any time according to the needs of the operation. In this embodiment, the pump body 3 with inflation and the control switch 4 that controls the opening and closing of the pump body 3 are both existing technologies and will not be described in detail.

[0032] Reference Figures 1-3 In a further embodiment, the pump body 3 is a miniature suction and air pump with a suction port 32. The connecting body 21 has a negative pressure airway 214, and the stripping head 22 has a negative pressure airway 222 that communicates with the negative pressure airway 214. The suction port 32 of the pump body 3 is plugged into and connected to the negative pressure airway 214. The control switch 4 can control the positive and negative pressure operation of the pump body 3. The pump body 3 has an outlet 33 that extends out of the outer wall of the handle 1 and is connected to an external pipe. During the operation, the surgical area will be filled with blood and fluid, affecting the surgeon's vision. The suction operation of the pump body 3 can generate negative pressure at the negative pressure airway 222 on the stripping head 22, thereby drawing in the blood and fluid and drawing it out through the outlet 33 on the pump body 3, thus making the surgical field of vision clear. In this embodiment, the miniature suction and air pump and the suction and extraction of liquid are existing technologies and will not be described in detail.

[0033] Reference Figures 1-3 The dissecting head 22 includes, but is not limited to, a disc-shaped or elliptical dissecting head 22.
