Abstract
The maxillary sinus mucous membrane protecting device comprises a maxillary sinus mucous membrane separating front surface of a clapboard and a plurality of supporting frames; one side of the supporting frame is respectively connected with the back of the partition board; the support frame is provided with through holes, the support frame is arranged along a straight line, and the through holes are connected in series to form a channel for the drill point to pass through. The utility model discloses a baffle separation drill point and maxillary sinus mucous membrane, maxillary sinus mucous membrane is rolled into the drill point and is twisted effectively in the prevention.
Description
Technical Field
The utility model relates to a medical instrument for implant surgery, in particular to a maxillary sinus mucous membrane protection device.
Background
The wing-threading dental implant operation is used for implanting the implant with a special length into cheekbones and pterygoid bones with the best bone quality of a human body so as to enhance the integral stability of the dental implant, reduce the requirement on the bone quantity of alveolar bones to a great extent and be beneficial to patients with maxillary dentition deficiency and serious shortage of residual bone quantity. The technical difficulty coefficient of the cheekbone implant is higher.
When the zygomatic implantation operation is carried out, the window is opened on the outer side wall of the maxillary sinus firstly, so as to separate the mucosa of the maxillary sinus. In the process of preparing holes step by step, a drill point with a blade part is very easy to roll the mucosa of the maxillary sinus into the hole, so that the mucosa of the maxillary sinus is damaged; thus, real-time intraoperative protection is required.
The patent CN201821481035.1 relates to a maxillary sinus mucous membrane protective sleeve for cheekbone implantation operation, the protective sleeve is of a sleeve structure, two rings are arranged on the side of the protective sleeve, the axes of the two rings are coaxial, and the axes of the two rings are parallel to the axis of the protective sleeve. The scheme can protect the mucosa of the maxillary sinus and adjacent soft and hard tissues and improve the operation safety. But the complete sleeve structure can shield the visual field of an operating doctor, so that the operation is inconvenient; the ring on the side of the sleeve increases the extra width, and has the possibility of scratching, which is not beneficial to the safety of the patient.
Disclosure of Invention
The utility model aims to solve the existing problems and provide a maxillary sinus mucous membrane protecting device.
In order to achieve the purpose, the utility model adopts the technical proposal that the utility model comprises a clapboard, the front of the clapboard is used for separating the mucosa of the maxillary sinus; one side of each support frame is connected with the back of the partition plate back to the maxillary sinus mucous membrane; the support frame is provided with through holes, the support frame is arranged along a straight line, and the through holes are connected in series to form a channel for the drill point to pass through.
Wherein, the cross section of the clapboard is a circular arc plate, and the convex protruding surface faces the mucosa of the maxillary sinus.
Wherein, the support frame is the ring, and one side of ring is connected with the back of baffle respectively.
Wherein, the other side of the circular ring is provided with an open type observation port.
Wherein, the support frame is vertically connected with the clapboard.
Wherein, still include the connecting rod, the one end and the support frame fixed connection of connecting rod.
Wherein the connecting rod and the channel form an included angle.
Wherein the included angle is 45 degrees.
Wherein, the other end of the connecting rod is connected with the handle.
Compared with the prior art, the utility model separates the drill point and the mucosa of the maxillary sinus by the clapboard, thereby effectively preventing the mucosa of the maxillary sinus from being wound by the drill point; the support frame is through and is connected with the connecting rod and the handle, so that the structure is simplified; the front surface of the circular arc-shaped partition board pushes away the mucosa of the maxillary sinus, and the back surface of the circular arc-shaped partition board forms the side wall of the channel; and the other side of the channel is open, which is beneficial to observation.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a schematic structural diagram of an embodiment of the present invention;
fig. 3 is a schematic structural diagram of an embodiment of the present invention;
referring to the attached drawings, a partition plate 1, a support frame 2, a connecting rod 3, a handle 4 and a channel 5.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1 and 3, fig. 1 and 3 show an embodiment of the present invention, which includes: a clapboard for pushing away and separating the mucosa of the maxillary sinus.
One side of each support frame is respectively connected with the back of the partition plate back to the mucosa of the maxillary sinus; the middle part of the support frame body is provided with a through hole. Because the support frames are arranged in a straight line and in parallel with each other, the five through holes can be connected in series to form a straight line, and a channel for the drill point to pass through is formed.
Preferably, the partition plate is an arc plate, the cross section of the partition plate is arc-shaped, and the axis of the arc is parallel to the channel; the arc protruding surface on the front surface of the clapboard faces the mucosa of the maxillary sinus. The front surface of the circular arc-shaped partition board pushes away the mucosa of the maxillary sinus, and the back surface of the circular arc-shaped partition board forms the side wall of the channel. Under the protection of the partition plate, the rotary drill bit extends into the passage for operation, perforation or rupture of mucous membrane of the maxillary sinus cannot be caused, and the safety of the operation is improved.
Further, referring to fig. 2, the outer frame of the support frame is a circular ring with a diameter of 3mm. One side (the half side facing to the mucosa of the maxillary sinus) of the circular ring is respectively and fixedly connected with the back of the clapboard; the other side of the ring (the half side back to the mucosa of the maxillary sinus) is not closed and is an open structure, so that an observation port for operation is formed.
In addition, the device also comprises a connecting rod, one end of the connecting rod is fixedly connected with the outer wall of the outer frame of the support frame, and the other end of the connecting rod is connected with a coaxial handle. Preferably, referring to fig. 1, the connecting rod body of the present embodiment forms an included angle of 45 degrees with the channel, which is more convenient for operation.
The embodiments of the present invention have been described in conjunction with the accompanying drawings and examples, the structures of which are not intended to limit the present invention, and those skilled in the art can make modifications as required, and all changes and modifications within the scope of the appended claims are within the scope of protection.
