[0030] Please refer to Figure 1 , Figure 2 and Figure 3 The hysteroscope of the present application comprises an insertion part 10, which comprises a tip 10a and an outer tube 10b and an inner tube 10c each in the shape of a long strip. The inner tube 10c is disposed in the outer tube 10b, the outer tube 10b provides a protective effect for the inner tube 10c, and ensures that the gap between the outer tube 10b and the inner tube 10c is left for the position of liquid delivery. The tip 10a can be, but is not limited to, a plastic structure or a silicone structure, so as to reduce the damage to the human body during the insertion of the insertion part 10, thereby better protecting the human body. In addition, the tip 10a is assembled and connected with the distal end 10b1 of the outer tube 10b and the distal end 10c1 of the inner tube 10c, respectively, so as to satisfy the tip 10a providing corresponding end sealing functions for the distal end 10b1 of the outer tube 10b and the distal end 10c1 of the inner tube 10c, as shown in Figure 2 .
[0031] In combination with Figure 4 and Figure 7, as an example, the tip head 10a comprises a tip body 11 and a first channel 12 formed in the tip body 11; the tip body 11 has oppositely arranged first and second end faces 111 and 112. The first channel 12 penetrates the first end face 111, extends towards the second end face 112, and further penetrates a side wall 113a of the tip body 11 adjacent to the second end face 112, so that a breach 114 is formed on the side wall 113a and opens laterally. Therefore, under the action of the breach 114, the instrument extending out of the first channel 12 is not limited by the side wall 113a on which the breach 114 is located, so that the instrument extending out of the first channel 12 can move freely on the side wall 113a, thereby increasing the operation space of the instrument. More specifically, as follows:
[0032] In combination with Figure 4 , Figure 6 and Figure 7 , as an example, the tip head 10a further comprises an expansion gap 13 formed in the tip body 11, the expansion gap 13 is used to expand the end of the first channel 12 adjacent to the second end face 112, and the expansion gap 13 further penetrates the second end face 112 and the side wall 113a. Therefore, by means of the expansion gap 13, on the one hand, the movement range of the instrument extending out of the tip body 11 is increased, and on the other hand, the operation of the instrument extending out of the tip body 11 or being pulled out of the tip body 11 is facilitated. Specifically, in Figure 7 , as an example, the tip body 11 has a curved surface 14 used to define the expansion gap 13, the curved surface 14 is arranged to be laterally convex towards the center C close to the second end face 112, for example, in Figure 7 , the curved surface 14 is arranged to be upwardly convex towards the center C close to the second end face 112, which design allows the instrument extending out of the tip body 11 to also move downwardly in Figure 7 , thereby further increasing the movement range of the instrument extending out of the tip body 11 and effectively reducing the damage to the human body; in addition, in Figure 6 , as an example, the curved surface 14 is arranged to be convex towards the center C close to the second end face 112 in the transverse direction (i.e., the direction of the plane of Figure 6 , which can provide a guiding effect for the instrument extending out of the tip body 11.
[0033] As Figure 7As shown, as an example, the tip head 10a further comprises a sleeve cavity 15 formed in the tip body 11, the sleeve cavity 15 is used to extend the end of the first channel 12 adjacent to the first end face 111, the sleeve cavity 15 further penetrates the first end face 111, and the sleeve cavity 15 is configured to be sleeved with the distal end 10c1 of the inner tube 10c to improve the assembly reliability of the tip body 11 and the distal end 10c1 of the inner tube 10c. Specifically, in combination with Figure 8 , as an example, the sleeve cavity 15 is flat, and the position of the first channel 12 corresponding to the sleeve cavity 15 is flat to better match the profile of the distal end 10c1 of the inner tube 10c.
[0034] In combination with Figure 4 , Figure 5 and Figure 8 , as an example, the tip head 10a further comprises a ring-shaped sunken ring groove 16 formed on the side wall of the tip body 11, the sunken ring groove 16 is arranged to extend around the side wall of the tip body 11, so that the tip body 11 and the distal end 10b1 of the outer tube 10b are flush with each other in the lateral direction after assembly by means of the sunken ring groove 16, avoiding the concave-convex defect in the lateral direction, so that the tip head 10 is more neat. Specifically, in combination with Figure 4 , Figure 5 and Figure 8 , as an example, the sunken ring groove 16 comprises a first groove segment 161 adjacent to the first end face 111, a second groove segment 162 adjacent to the second end face 112, and a third groove segment 163 connected between the first groove segment 161 and the second groove segment 162, the second groove segment 162 and the third groove segment 163 are arranged opposite to the break 114, and the first groove segment 161 is arranged on the same side as the break 114, for example, in Figure 5 , the first groove segment 161 and the break 114 are both arranged upward; alternatively, in Figure 5 , as an example, the first groove segment 161 and the second groove segment 162 are both curved, and the third groove segment 163 is linear; this design can increase the joint circumference of the tip body 11 and the distal end 10b1 of the outer tube 10b, thereby improving the stability of the assembly between the tip body 11 and the distal end 10b1 of the outer tube 10b.
[0035] In combination with Figure 4 , Figure 5 and Figure 8 , as an example, the tip head 10a further comprises an embedded cavity 17 for embedding and installing an external camera module, the embedded cavity 17 is formed on a position 115 of the tip body 11 surrounded by the sunken ring groove 16 and opposite to the break 114, and an exposed hole 1121 is formed on the second end face 112 for exposing the camera module to meet the shooting needs of the camera module.
[0036] Compared with the prior art, since the first channel 12 also penetrates the end head body 11 adjacent to the one side wall 113a of the second end face 112, so that the one side wall 113a is surrounded by the break 114 which is open from the side, the design makes the operation space of the instrument which extends from the first channel 12 on the one side wall 113a of the end head body 11 where the break 114 is located to be large, effectively reducing the constraint of the end head body 11 to the movement of the instrument.
[0037] It is additionally explained that the distal end 10b1 (10c1) of the outer tube 10b and the inner tube 10c both refers to the end which is far away from the operator.
[0038] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims.
