[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a connective tissue hyperplasia removal mechanism to solve the problems existing in the above-mentioned prior art and to improve the effect of connective tissue hyperplasia removal.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Currently, most doctors perform blind surgery when removing connective tissue hyperplasia. There is no visual camera, and the results of the surgery depend on the doctor's experience. The results of the surgery vary greatly among different doctors.

[0031] In order to solve the above technical problems, the present invention provides a connective tissue hyperplasia removal mechanism, such as Figure 1 , Figure 2 , Figure 3As shown, it includes a resection mechanism body, an outer knife assembly, an inner knife assembly and a visual assembly; the resection mechanism body includes a sleeve 1, an inner knife assembly is arranged in the sleeve 1, the outer knife assembly is fixedly arranged at one end of the sleeve 1 of the resection mechanism body, and the outer knife assembly is provided with an inner knife channel with a side wall opening 401, a hollow cavity is arranged in the outer knife assembly, the cavity forms the inner knife channel, and the inner knife channel is provided with a through hole at one end close to the resection mechanism body, so that the inner knife assembly can enter the inner knife channel through the through hole, the opening 401 on the side wall of the outer knife assembly is an opening 401 of a strip structure arranged along the axis of the outer knife assembly, and the virtual plane where the opening 401 is located extends along the radial direction of the outer knife assembly toward the axis until it is close to the axis position of the outer knife assembly, and a cutting head 402 is provided at one end of the outer knife assembly away from the through hole, which can cut a small hole in the surgical area, so that the inner knife assembly can enter the small hole position and rotate and cut; the inner knife assembly is arranged in the resection mechanism body, and one end of it can enter the inner knife channel and rotate and cut the connective tissue growth at the opening 401 of the inner knife channel. The inner knife assembly is coaxially arranged with the outer knife assembly, and the virtual plane where the opening 401 is located is located near the axis position of the outer knife assembly, so a part of the cutting edge of the side wall of the end of the inner knife assembly extends from the opening 401 to the outside of the opening 401, that is, the cutting edge on one side of the inner knife assembly is always located in the inner knife channel, and the cutting edge on the other side is always located outside the inner knife channel. When the inner knife assembly rotates, the connective tissue hyperplasia at the location can be removed; the visual assembly includes an imaging end and a lens 6, and the lens 6 is fixed to one side of the outer knife assembly, and can transmit a real-time image of the cutting area to the imaging end, so that the doctor can observe the cutting area in real time during the cutting operation, and can not only see the remaining situation of the connective tissue hyperplasia, but also see the rotation state of the inner knife assembly, and can manually judge the rotation speed of the inner knife assembly intuitively according to the rotation state, so as to help the doctor to cut accurately, and can judge the amount of each cutting according to the real-time image displayed by the imaging of the cutting area, so that the cutting position is more accurate, the cutting amount is easier to control, and the effect of the removal of connective tissue hyperplasia is improved.

[0032] The imaging component of this embodiment belongs to the prior art, and the specific structure is not limited. In one embodiment, the lens 6 is similar to a real-time miniature camera, and the image of the lens 6 is transmitted to the imaging end in real time by optical fiber. In another embodiment, the imaging component can adopt a laparoscope or endoscope structure. The lens 6 of the laparoscope or endoscope adopts an optical lens, which is fixed on one side of the external knife assembly. The imaging end includes an image sensor and a display, which are tilted and fixed on the resection mechanism body.

[0033] In the prior art, if the doctor wants to perform the operation under visual conditions, multiple holes or one large hole must be opened in the affected area to accommodate the cutting equipment and the imaging equipment respectively. This is not in line with the original intention of minimally invasive surgery. In addition, the cutting equipment and the imaging equipment are arranged separately, and the simultaneous handheld operation of multiple devices also greatly affects the operation time and the operation effect. In order to solve this problem, in this embodiment, a connecting tube 2 with a smaller diameter is fixed at one end of the sleeve 1, and the outer knife assembly is fixed at the end of the connecting tube 2 away from the sleeve 1, and one end of the inner knife assembly passes through the connecting tube 2 and enters the inner knife channel of the outer knife assembly. The outer knife assembly of this embodiment includes an outer knife body 4, one side of the outer knife body 4 is provided with an opening 401 arranged along the axial direction, and the end of the outer knife body 4 is provided with a cutting head 402 with a smooth arc structure, and the cutting head 402 is convenient for cutting into the area to be cut; the diameter of the outer knife body 4 is less than 6mm, and the length is 12mm. The lens 6 is fixedly attached to one side of the outer knife body 4, and the length of the lens 6 is 5mm. The smaller lens 6 and the outer knife body 4 are combined into one, which greatly reduces the size of the hole in the affected area, and no scar will appear on the affected area after surgery. The imaging end is fixed to the upper part of the sleeve 1. The doctor only needs to hold the sleeve 1 to realize the dual functions of surgery and observation, and the lens 6 will move with the outer knife body 4 in real time, and can display the image of the actual surgical area in real time, without the need to hold different multiple devices and operate simultaneously.

[0034] In order to achieve rapid removal of connective tissue hyperplasia, the inner knife assembly of this embodiment includes a driving part and an inner knife body 5. The driving part can be a motor. The driving part of this embodiment is an electric motor, which is fixed in the sleeve 1, and a control switch 9 is provided on the outer wall of the sleeve 1. The control switch 9 is electrically connected to the electric motor and can control the start and stop of the electric motor. The rotation speed of the output end of the electric motor can also be controlled by the control switch 9. The output end of the electric motor is connected to the inner knife body 5 in a transmission manner, and the end of the inner knife body 5 extends to the opening 401 side of the outer knife assembly. A serrated cutting blade 501 is fixedly provided at the side wall of the end of the inner knife body 5, and the cutting blade 501 extends to the outside of the opening 401 side of the inner knife body 5, and can rotate and cut on the opening 401 side of the outer knife assembly.

[0035] The lens 6 of this embodiment is fixed to one side of the outer knife body 4 and arranged parallel to the axis of the outer knife body 4, and the monitoring end of the lens 6 is slightly inclined toward the axis direction of the outer knife body 4, so that the observation field of the lens 6 is toward the opening side of the outer knife body 4, and the monitoring end of the lens 6 is an inclined surface structure arranged along the axis of the lens, and the angle between the inclined surface and the axis of the lens is 30°, so that the surface area of ​​the monitoring end is larger, and the field of view of the lens 6 during monitoring is expanded. Since the inclined surface structure of the monitoring end of the lens has a wider field of view than the traditional hole structure or circular surface structure, more areas can be observed and monitored, and the images of the observed and monitored areas can be transmitted to the imaging end in real time. During surgery, not only the remaining connective tissue hyperplasia can be seen in the field of view of the lens 6, but also the rotation state of the inner knife body 5 on the opening side can be seen, which helps the doctor to accurately judge the amount of cutting each time.

[0036] In the existing surgical structure, both the outer knife and the cutting inner knife are inserted into a cylindrical handle, which is inconvenient to use; the present invention combines and fixes the outer knife body 4 and the lens 6 as a whole, and then installs them at the end of the connecting tube 2, and only the inner knife body 5 is movably inserted in the sleeve 1. The outer knife body 4 cuts into the surgical area to form a tiny incision, and then remains fixed. After the tiny incision is formed, the control switch is turned to turn on the electric motor, and the inner knife body 5 is driven by the electric motor to rotate to cut the incision. There will be no interference between the outer knife body 4 and the inner knife body 5, making the doctor's operation more convenient.

[0037] In order to facilitate observation, the imaging end of this embodiment includes an imaging seat 7 fixed on the sleeve 1, and an observation window 8 is provided at an angle above the imaging seat 7. An imaging lens is provided at the observation window 8. The doctor can observe the image transmitted from the lens 6 through the optical fiber in real time through the observation window 8; a focusing knob 10 is provided on the imaging seat 7, and the focusing knob 10 can adjust the focal length at the observation window 8 to make the field of view clearer.

[0038] Since a visual component is provided, the device of this embodiment can observe the situation in the surgical area more clearly during surgery. In order to facilitate the doctor to adjust the surgical cutting process in time according to the observed image, in one embodiment, a gripping handle 3 is fixedly provided on the bottom side wall of the sleeve 1. The handheld structure is adopted, which greatly reduces the doctor's discomfort in operation, is more ergonomic, and is convenient for the doctor to adjust the cutting position and cutting depth in time.

[0039] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
