Description

Technical Field

[0001] The invention relates to a visual puncture device. Background Art

[0002] The puncture device is an essential instrument for establishing a surgical channel and an observation channel in abdominal surgery. The puncture device usually includes an outer sheath tube as a channel for other surgical instruments to enter and a puncture rod that runs through the outer sheath tube. First, in order to penetrate the skin, the skin epidermis is cut with a scalpel, and then the puncture rod is used to penetrate the skin and enter the body cavity together with the outer sheath tube, and then the puncture rod is pulled out, and the outer sheath tube can be used as a channel for introducing various instruments and tools into the abdominal cavity. In the prior art, most puncture devices are not equipped with cameras and searchlights, and laparoscopes (optical test tubes) are used to achieve monitoring needs. After the laparoscope is withdrawn, the abdominal cavity will inevitably lose monitoring, and there are certain safety hazards. Or there are other technical puncture devices. The camera and searchlight are both set on the puncture rod to observe the position and condition of the puncture in real time, but when the puncture is completed and the puncture rod is removed, the medical staff needs to observe the subsequent surgical operations with the assistance of the laparoscope, so that it is impossible to reduce the puncture hole and achieve the purpose of reducing the wound. There is a type of puncture device with a camera installed on the outer sheath. Although it can be used to observe the internal body conditions in real time after the puncture rod is removed, because the camera is fixed on the wall of the outer sheath, it is easy to block the camera's field of view when the instrument enters, thereby affecting the surgical viewing angle. Summary of the invention

[0003] The object of the present invention is to provide a visual puncture device which can observe the surgical scene at any time and adjust the shooting angle at any time according to actual needs.

[0004] The objective of the present invention is achieved through the following technical scheme: a visual puncture device, which comprises a sheath assembly, a puncture rod and a camera assembly; the sheath assembly comprises an outer sheath that passes through from top to bottom, and the puncture rod is placed in the passage of the outer sheath; the camera assembly is placed in the passage of the outer sheath and can rotate an angle in the passage of the outer sheath.

[0005] Compared with the prior art, the advantages of the present invention are:

[0006] 1. The visual puncture device of the present invention can be used to establish a surgical channel, and its camera assembly can not only rotate in the horizontal direction, but also move in the longitudinal direction. Therefore, the visual puncture device can observe the surgical scene at any time and adjust the shooting angle at any time according to actual needs, so that the operation can be carried out better.

[0007] 2. The visual puncture device can reduce the number of surgical incisions, thereby reducing the trauma of the patient and reducing the incidence of infection.

[0008] 3. The camera of the visual puncture device is arranged on the bottom surface of the base and the bottom surface of the base is an inclined surface. Such a design allows the camera to have a wider viewing angle, will not block the camera's shooting field of view, and can better provide a surgical scene. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0028] Embodiment 1:

[0029] like Figures 1 to 14 Shown is a schematic diagram of an embodiment of a visual puncture device provided by the present invention.

[0030] The visual puncture device includes a sheath assembly, a puncture rod 2 and a camera assembly 3; the sheath assembly includes an outer sheath 11 that passes through from top to bottom, and the puncture rod 2 is placed in the passage of the outer sheath 11; the camera assembly 3 is placed in the passage of the outer sheath 11 and can rotate at an angle in the passage of the outer sheath 11.

[0031] The sheath assembly also includes a sheath seat 12 disposed at the upper end of the outer sheath 11 , and the sheath seat 12 is provided with a through hole A121 communicating with the passage of the outer sheath 11 , and the puncture rod 2 and the camera assembly 3 enter the passage of the outer sheath 11 through the through hole A121 of the sheath seat 12 .

[0032] The camera assembly 3 includes a rotating shaft 31, a base 32 connected to the lower end of the rotating shaft 31, a camera 33 fixed on the base 32, a display 34 connected to the camera 33, and a control member vertically connected to the upper end of the rotating shaft 31;

[0033] The sheath assembly also includes a top cover 13 disposed above the sheath seat 12 and detachably connected to the sheath seat 12; a through hole B132 corresponding to the through hole A121 is provided on the top cover 13, and a guide hole 131 for accommodating the control member to pass through is provided on the side wall of the top cover 13; by controlling the control member, the base 32 is rotated to adjust the angle of the camera 33.

[0034] The sheath tube seat 12 and the top cover 13 are both provided with a sealing structure. Since the sealing structure is a conventional structure of the trocar, the present invention does not elaborate too much on the specific structure of the sealing structure. Of course, the outer sheath tube 11 is also provided with some conventional structures of the trocar, such as an air injection valve, etc.

[0035] The sheath tube seat 12 and the top cover 13 can be detachably connected by means of threaded connection or buckled connection.

[0036] The angle adjustment range of the camera 33 is 0-180°.

[0037] The bottom surface of the base 32 is an inclined surface, and the camera 33 is arranged on the bottom surface of the base 32. The camera of the visual puncture device is arranged on the bottom surface of the base and the bottom surface of the base is an inclined surface. Such a design allows the camera 33 to have a wider viewing angle, does not block the shooting field of the camera 33, and can better provide a surgical scene.

[0038] The camera 33 and the display 34 are connected via a data line 36. Of course, the camera 33 and the display 34 can also be connected wirelessly.

[0039] The camera assembly 3 also includes an LED light on the base 32 .

[0040] A circuit board may be disposed on the base 32, the camera 33 and the LED light are connected to the circuit board, and the data line 36 is connected to the circuit board to transmit the scene captured by the camera 33 to the display 34. Since the connection method between the circuit board and the LED light is a prior art, the LED light is not marked in the drawings of the present invention.

[0041] The LED lamp provides lighting, and the camera 33 is used to take real-time photos and display the captured scenes on the display 34, so as to better restore the operation scene. The medical staff can observe the location and status of the operation in real time, ensuring that the operation can be carried out smoothly and safely.

[0042] The control member is a lever 35 , and the guide hole 131 is arc-shaped. The lever 35 is pushed along the guide hole 131 to rotate the base 32 and adjust the angle of the camera 33 .

[0043] The camera assembly 3 further includes an adjustment unit for enabling the base 32 to slide in the longitudinal direction; the adjustment unit includes an adjustment rod 37 extending longitudinally and a tilting rod 38 hinged to the upper end of the adjustment rod 37 and extending through the guide hole 131;

[0044] The rotating shaft 31 is provided with a downwardly penetrating channel, and the adjusting rod 37 is fixedly connected to the base 32 through the channel of the rotating shaft 31. The outer wall surface of the bottom end of the rotating shaft 31 is provided with a protrusion 311 extending outward, and the base 32 is provided with a sliding groove extending longitudinally to allow the protrusion 311 to slide.

[0045] Since it is a conventional technology that the protrusion 311 slides along the slide groove, the slide groove is not marked in the drawings of the present invention.

[0046] When the tilting rod 38 is pried downward, the adjusting rod 37 moves upward, thereby driving the base 32 to move upward. The rotating shaft 31 forms a sliding connection with the base 32 through its own protrusion 311 and the sliding groove on the base 32, so the base 32 can slide up and down under the drive of the adjusting unit.

[0047] The data line 36 is connected to the camera 33 through the channel of the rotating shaft 31 , and the upper end of the data line 36 is connected to the display 34 .

[0048] The lever 35 is provided with a limit groove extending in the left-right direction and opening upward, and the tilting rod 38 is placed in the limit groove and the right end of the tilting rod 38 extends out of the limit groove. Such a structure can form a fulcrum on the lever 35 for the tilting rod 38 to swing up and down. Of course, the lever 35 can be provided with another fulcrum for the tilting rod 38 to swing up and down.

[0049] The lever 35 and the rotating shaft 31 of the present invention can rotate the base 32 in the horizontal direction to control the shooting angle of the camera 33; the tilting rod 38 controls the up and down movement of the adjusting rod 37, which can drive the base 32 to move longitudinally. The lever 35 and the rotating shaft 31, the tilting rod 38 and the adjusting rod 37 cooperate to enable the camera 33 to capture the surgical scene well, thereby allowing the surgery to be carried out better.

[0050] The method of using the visual puncture device is as follows: first, place the puncture rod 2 in the passage of the outer sheath tube 11, then insert the puncture device with the puncture rod 2 into the human body, and then withdraw the puncture rod 2; then, remove the top cover 13, then insert the camera assembly 3 into the passage of the outer sheath tube 11, and place the lever 35 and the tilting rod 38 in the guide hole 131, then cover the top cover 13, and fix the camera assembly 3; then, move the lever 35 along the guide hole 131 of the top cover 13 to rotate the base 32, so that the base 32 deviates from the passage of the outer sheath tube 11, as shown in FIG. Fig.11 As shown, the instrument can enter and exit the passage of the outer sheath 11 to perform surgery. Of course, during the operation, the lever 35 can be moved at any time as needed to adjust the angle of the camera 33; the lever 38 can also be moved up and down to make the base 32 slide up and down, thereby adjusting the position of the base 32, the camera 33 and the LED light.

[0051] Embodiment 2: Figures 15 to 17The second embodiment is substantially the same as the first embodiment, the main difference being that the connection between the rotating shaft 31 and the control member is different, and the second embodiment does not include an adjustment unit for making the base 32 slide in the longitudinal direction.

[0052] In the second embodiment, the control member is a connecting shaft 39, and the guide hole 131 is a circular hole for accommodating the connecting shaft 39 to pass through; a gear A391 is provided at the left end of the connecting shaft 39, and a gear B40 vertically meshing with the gear A391 is provided at the upper end of the rotating shaft 31. The connecting shaft 39 is rotated with the central axis of the connecting shaft 39 as the rotating axis, thereby driving the gear A391 to rotate, and then driving the base 32 to rotate through the gear B40; the base 32 rotates to adjust the angle of the camera 33.

[0053] A knob 392 is disposed at the right end of the connecting shaft 39 , and the rotation of the base 32 is controlled by rotating the knob 392 .

[0054] It should be noted that the above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several changes, improvements and modifications without departing from the concept of the present invention. These changes, improvements and modifications should also be regarded as the scope of protection of the present invention.
