Description

Technical Field

[0001] The utility model relates to the field of clamping device, in particular to an air pressure-controlled valve type artificial ossicular implantation clamping device. Background Art

[0002] Conductive hearing loss (cause includes otitis media, otosclerosis, ossicular chain deformity, etc.) is a common middle ear disease in clinical practice, which affects patients' daily communication. Ossicular chain reconstruction surgery is an effective method for treating conductive hearing loss, and various artificial ossicular prostheses are often needed in clinical practice. Ossicular prostheses are tiny, and special care must be taken when clamping them to avoid dropping or breaking them. The use of existing microsurgical forceps requires the use of the strength of the fingers, palms and wrists, and the flexibility of clamping the artificial ossicles is poor. Novice hands are prone to shaking, and they are also prone to conflict with the otoscope in the narrow ear canal. When placing the artificial ossicles on the stapes head or base plate, if the hand strength and direction are not properly controlled, the stapes or base plate may be damaged. Moreover, when the hands are tense, opening the surgical forceps and loosening the artificial ossicles too much may also cause them to shift. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art. The utility model proposes an air pressure-controlled valve-type artificial ossicular implant holder, which can stably fix and place the ossicular prosthesis, thereby facilitating stable transportation to a preset position.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a pneumatic valve-controlled artificial ossicular implant holder, comprising:

[0005] A circular tube, wherein a partition is fixedly connected inside the circular tube, so that the circular tube is divided into a first gas channel and a second gas channel which are not connected to each other;

[0006] The side wall of the circular tube is provided with a first side hole and a second side hole, the first side hole is connected to the first gas channel, and the second side hole is connected to the second gas channel;

[0007] A first conical groove is formed on the left side of the partition, a second conical groove is formed on the left side of the circular tube, first semi-arc grooves are formed on the upper and lower parts of the first conical groove, and third semi-arc grooves are formed on the upper and lower parts of the outer wall of the circular tube, and the two first semi-arc grooves are respectively connected to the two third semi-arc grooves;

[0008] It also includes a conical plate, and the outer wall of the circular tube is connected to a swingable conical plate. The upper and lower parts of the right side of the conical plate are both provided with a second semi-arc groove. The second semi-arc groove on the upper part cooperates with the first semi-arc groove and the third semi-arc groove on the upper part to fix the ossicular prosthesis. The upper part of the conical plate cooperates with the left part of the first gas channel. The first gas channel is connected with vacuum suction to adsorb the conical plate at the first gas channel, so that the ossicular prosthesis is stably fixed.

[0009] Furthermore, the outer wall of the circular tube is rotatably connected to a rotating column, the outer wall of the rotating column is fixedly connected to a connecting plate, and the side of the connecting plate away from the rotating column is fixedly connected to the conical plate.

[0010] Furthermore, the lower portion of the conical plate can cooperate with the left portion of the second gas channel, and the second gas channel is introduced with a vacuum force to allow the lower portion of the conical plate to be adsorbed onto the second gas channel. When the first side hole is loosened and the second side hole is pressed, the fixation of the ossicular prosthesis is released, and the conical plate is stably placed at the second gas channel to prevent the conical plate from causing displacement of the ossicular prosthesis.

[0011] Furthermore, two vacuum pipe joints are fixedly installed on the right side of the circular tube, the two vacuum pipe joints are respectively connected to the first gas channel and the second gas channel, and the two vacuum pipe joints are both connected to an external vacuum suction pipe.

DETAILED DESCRIPTION

[0023] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0024] Example:

[0025] like Figure 1-5 As shown, a partition plate 2 is fixedly connected to the inner wall of the circular tube 1, so as to form a first gas channel 3 and a second gas channel 4 in the circular tube 1, and the first gas channel 3 and the second gas channel 4 are not connected to each other. Two vacuum pipe joints 5 are fixedly installed on the right side of the circular tube 1, and the two vacuum pipe joints 5 are respectively connected to the first gas channel 3 and the second gas channel 4, and the two vacuum pipe joints 5 are connected to the vacuum tube outside.

[0026] A first conical groove 8 is opened on the left side of the partition 2, and a first semi-arc groove 9 is opened on the upper and lower parts of the first conical groove 8. A second conical groove 10 is opened on the left side of the circular tube 1, and a third semi-arc groove 16 is opened on the upper and lower parts of the left side of the circular tube 1. The upper third semi-arc groove 16 is connected to the upper first semi-arc groove 9, and the lower third semi-arc groove 16 is connected to the lower first semi-arc groove 9.

[0027] The outer wall of the circular tube 1 is rotatably connected to a rotating column 13 , the outer wall of the rotating column 13 is fixedly connected to a connecting plate 12 , and a conical plate 11 is fixedly connected to a side of the connecting plate 12 away from the rotating column 13 .

[0028] The upper and lower parts of the conical plate 11 are both provided with a second semi-arc groove 14, and the conical plate 11 is made of rubber material.

[0029] The second upper semi-arc groove 14 and the first upper semi-arc groove 9 and the third semi-arc groove 16 are used to compress the ossicular prosthesis 15, and the upper part of the conical plate 11 cooperates with the vacuum adsorption of the left part of the first gas channel 3 to enable the left side of the first gas channel 3 to adsorb and fix the upper right part of the conical plate 11.

[0030] The lower second semi-arc groove 14 cooperates with the lower first semi-arc groove 9 and the third semi-arc groove 16 to form another station for fixing the ossicular prosthesis 15. The corresponding lower second semi-arc groove 14 cooperates with the lower first semi-arc groove 9 to fix the ossicular prosthesis 15 at the second station.

[0031] In the specific implementation, firstly, the two vacuum pipe joints 5 are connected to the external vacuum pipe, and then the ossicular prosthesis 15 is clamped between the second semi-arc groove 14 and the first semi-arc groove 9 at the upper part. At this time, the first side hole 6 connected to the upper part of the first gas channel 3 is blocked by fingers, and the first gas channel 3 forms a stable vacuum adsorption, so that the left side of the first gas channel 3 adsorbs the upper part of the conical plate 11 to the left part of the first gas channel 3. The conical plate 11 is made of rubber material, which can stably block the left part of the first gas channel 3 with the conical plate 11, and the conical plate 11 is stably placed on the left part of the first gas channel 3. At this time, the fixation of the ossicular prosthesis 15 is completed, and it can be transported to the preset position.

[0032] When the ossicular prosthesis 15 is transported to the preset position, the first side hole 6 connected to the first gas channel 3 is released, and the second side hole 7 connected to the second gas channel 4 is blocked with a finger, so that the second gas channel 4 forms a vacuum, and the lower part of the conical plate 11 is adsorbed on the left side of the second gas channel 4 and fixed. At this time, the ossicular prosthesis 15 is released, and the conical plate 11 will not swing at will to affect the ossicular prosthesis 15, so that the ossicular prosthesis 15 is stably placed in the preset position.

[0033] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
