Description

Technical Field

[0001] This utility model relates to a medical device, and more particularly to a hysteroscope with a variable handle shape. Background Technology

[0002] As is well known, hysteroscopic surgery is a minimally invasive procedure with short recovery time, short operation duration and low cost, and hysteroscopic surgery is inseparable from the use of hysteroscopes.

[0003] Currently, for example, in the hysteroscope and its fluid return mechanism disclosed in Chinese Patent Application No. 202421265388.3, ​​its shell (i.e., handle structure) is a fixed, bent shape. Although the bent shell facilitates static observation and operation by the operator, the shell is frequently rotated during use to adjust the orientation of the insertion tip within the uterine cavity. However, the bent shell makes it inconvenient for the operator to rotate it. Therefore, the hysteroscope and its fluid return mechanism disclosed in Chinese Patent Application No. 202421265388.3 cannot meet the different operational needs of clinical practice.

[0004] Therefore, there is an urgent need for a hysteroscope with a variable handle shape to overcome one or more of the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a hysteroscope with a variable handle shape to meet different clinical operation needs.

[0006] To achieve the above objectives, the variable-shape hysteroscope of this invention includes a handle and an elongated insertion portion. The tail end of the insertion portion is mounted on the handle, and the head end of the insertion portion is away from the handle. The handle includes a first handle module for mounting the tail end of the insertion portion and a second handle module movably mounted on the first handle module. The second handle module is movable relative to the first handle module between a first position and a second position, and the shape of the handle is changed accordingly by the movement of the second handle module between the first and second positions.

[0007] Compared with the prior art, since the handle includes a first handle module for mounting and connecting the tail end of the insertion part and a second handle module movably mounted on the first handle module, the second handle module can move relative to the first handle module between a first position and a second position. Therefore, by moving the second handle module between the first position and the second position, the shape of the handle can be changed accordingly to meet different clinical operation needs, such as the needs of static observation operation and rotation operation.

[0008] Preferably, when the second module of the handle is moved to the first position, it forms a bent shape together with the first module of the handle.

[0010] Preferably, the second module of the handle is pivotally connected to the first module of the handle via a pivot structure, and the second module of the handle pivots about the axis of the pivot structure during its movement between the first position and the second position.

[0011] Preferably, the first module of the handle has a first lug protruding at its tail end, and the second module of the handle has a second lug protruding at its head end. One of the first lug and the second lug has an insert cavity, and the other of the first lug and the second lug is at least partially inserted into the insert cavity. The pivot structure pivotally connects the second lug to the first lug.

[0012] Preferably, the first or second module of the handle where the mounting cavity is located has a first limiting surface and a second limiting surface arranged spaced apart in the pivoting direction of the second module of the handle, the first limiting surface and the second limiting surface being exposed in the mounting cavity; when the second module of the handle moves to the first position, the first lug or the second lug fitted in the mounting cavity abuts against the first limiting surface; when the second module of the handle moves to the second position, the first lug or the second lug fitted in the mounting cavity abuts against the second limiting surface.

[0013] Preferably, the variable handle hysteroscope of this invention further includes a damping ring arranged around the pivot structure, the damping ring being compressed in the axial direction of the pivot structure between the first lug and the second lug.

[0014] Preferably, the first lug or the second lug has an annular mounting groove arranged around the pivot structure, and the damping ring is partially mounted in the mounting groove.

[0015] Preferably, the first module of the handle is provided with an exposed inlet connector, a return connector, and an instrument inlet / outlet connector.

[0016] Preferably, the tail end face of the first module of the handle has a first inclined surface, and the second lug is provided with a second inclined surface opposite to the first inclined surface. When the second module of the handle moves to the second position, the second inclined surface is arranged in an inverted "V" shape with the first inclined surface, and the instrument inlet / outlet connector is located on the first inclined surface.

[0017] Preferably, the inlet connector and the return connector are arranged on opposite sides of the first module of the handle. Attached Figure Description

[0032] Please see Figures 1 to 6 The variable handle hysteroscope 100 of this utility model includes a handle 10 and an elongated insertion part 20. The tail end 21 of the insertion part 20 is mounted on the handle 10, and the handle 10 provides support for the insertion part 20. The head end 22 of the insertion part 20 is away from the handle 10 to meet the required length of the insertion part 20. Since the specific structure of the insertion part 20 is well known in the art, please refer to the hysteroscope and its fluid return mechanism disclosed in Chinese Patent Application No. 202421265388.3, ​​so it will not be described in detail here.

[0033] The handle 10 includes a first handle module 11 for mounting to the tail end 21 of the insertion portion 20, and a second handle module 12 movably mounted on the first handle module 11. The second handle module 12 can at least be positioned relative to the first handle module 11 as follows: Figures 1 to 3 The first position shown and as Figures 4 to 6 The second position shown is movable; therefore, by moving the second module 12 of the handle between the first and second positions, the shape of the handle 10 is changed accordingly; alternatively, in Figures 1 to 3 In this example, when the second module 12 of the handle is moved to the first position, it forms a bent shape together with the first module 11 of the handle. Preferably, the second module 12 of the handle is arranged at an obtuse angle relative to the first module 11 of the handle, which facilitates static observation and operation by the operator. Furthermore, in... Figures 4 to 6 In this example, when the second module 12 of the handle is moved to the second position, it forms a straight shape together with the first module 11 of the handle to facilitate the operator's rotation of the handle 10. More specifically, as follows:

[0034] like Figures 1 to 4 and Figures 6 to 12 As shown, as an example, the second module 12 of the handle is pivotally connected to the first module 11 of the handle via a pivot structure 30, so that the second module 12 of the handle can pivot about the axis 31 of the pivot structure 30 during its movement between the first position and the second position. Since the second module 12 of the handle switches between the first position and the second position by pivoting, the defect of increased lateral size of the first module 11 caused by the second module 12 of the handle being mounted to the first module 11 by a sliding telescopic method is avoided, and the ease of movement of the second module 12 of the handle relative to the first module 11 is also facilitated. Furthermore, since the second module 12 of the handle switches between the first position and the second position by pivoting, the second module 12 of the handle pivoted to the second position extends the length of the first module 11 of the handle in the length direction of the insertion portion 20. Specifically, in Figures 1 to 4 and Figures 6 to 12 As an example, the first module 11 of the handle has a first lug 111 protruding from its tail end 11a, and the first lug 111 has an insert cavity 112; the second module 12 of the handle has a second lug 121 protruding from its head end 12a, and the second lug 121 is partially fitted into the insert cavity 112, as shown in the figure. Figure 1 As shown; at this time, the pivot structure 30 pivots the second lug 121 to the first lug 111; this design allows the second module 12 of the handle to pivot a large range relative to the first module 11 of the handle around the axis 31.

[0035] In order to avoid the pivoting transition of the second module 12 of the handle relative to the first module 11 of the handle, Figure 12 As an example, the first module 11 of the handle, where the mounting cavity 112 is located, has a first limiting surface 113 and a second limiting surface 114 arranged spaced apart in the pivoting direction of the second module 12 of the handle. The first limiting surface 113 and the second limiting surface 114 are exposed in the mounting cavity 112. Therefore, when the second module 12 of the handle moves to the first position, the second lug 121 fitted in the mounting cavity 112 abuts against the first limiting surface 113, as shown in the figure. Figure 2As shown; when the second module 12 of the handle moves to the second position, the second lug 121, which is fitted into the fitting cavity 112, abuts against the second limiting surface 114, as shown in the figure. Figure 10 As shown. To enable the second module 12 of the handle to have a hovering function when pivoted to any position relative to the first module 11 of the handle, in... Figure 7 , Figure 8 , Figure 9 and Figure 12 As an example, the variable handle hysteroscope 100 of this utility model also includes a damping ring 40 arranged around the pivot structure 30. The damping ring 40 is also compressed between the first lug 111 and the second lug 121 in the axial direction of the pivot structure 30 (see the direction indicated by arrow B and the opposite direction). Therefore, the damping ring 40 provides a certain holding force for the second module 12 of the handle when it is pivoted into place, effectively preventing the handle 10 from deforming itself. Alternatively, in Figure 7 In this example, the first lug 111 has an annular mounting groove 115 arranged around the pivot structure 30. The damping ring 40 is partially mounted in the mounting groove 115. This design fixes the damping ring 40 to the first module 11 of the handle. Since the first module 11 of the handle is generally stationary relative to the second module 12 of the handle, it avoids the damping ring 40 being mounted on the second module 12 of the handle and pivoting with it, thus avoiding the relatively poor stability caused by pivoting together. Furthermore, in... Figure 7 In this configuration, there are two damping rings 40 spaced apart axially in the pivot structure 30. Correspondingly, there are also two mounting grooves 115, so that one damping ring 40 is fitted into its corresponding mounting groove 115. It should be noted that, although... Figure 7 The illustration shows that the fitting groove 115 is formed by the first lug 111. Of course, depending on actual needs, the fitting groove 115 can also be formed by the second lug 121, so it is not considered as such. Figure 7 The above is the limit; also, although Figure 12 The illustration shows that the fitting cavity 112 is formed by the first lug 111. Obviously, depending on actual needs, the fitting cavity 112 can also be formed by the second lug 121, so it is not considered as such. Figure 12 The above is the limit; in addition, although Figure 7 The diagram shows that the pivot structure 30 is an independent component passing through the first lug 111 and the second lug 121. Obviously, depending on actual needs, the pivot structure 30 can also be formed from a portion of the first lug 111 or the second lug 121; therefore, it is not considered... Figure 7 The above is the limit.

[0036] Combination Figures 1 to 12As an example, the first module 11 of the handle is provided with an exposed inlet connector 13, a return connector 14, and an instrument inlet / outlet connector 15, so that the inlet connector 13, the return connector 14, and the instrument inlet / outlet connector 15 are independent of each other, and therefore, when an external instrument enters through the instrument inlet / outlet connector 15, it does not affect the inlet operation. Specifically, in Figure 5 In this example, the inlet connector 13 and the return connector 14 are arranged opposite each other on the first module 11 of the handle. This arrangement provides more space around the inlet connector 13 and the return connector 14, facilitating the connection of external components to them. Figure 6 As an example, the tail end face of the first module 11 of the handle has a first inclined surface 116, and the second lug 121 has a second inclined surface 1211 opposite to the first inclined surface 116. When the second module 12 of the handle moves to the second position, the second inclined surface 1211 and the first inclined surface 116 are arranged in an inverted "V" shape, as shown in the figure. Figure 6 As shown, at this time, the instrument inlet / outlet connector 15 is located on the first inclined surface 116. This design provides sufficient clearance for external instruments inserted into the instrument inlet / outlet connector 15 when the second module 12 of the handle is moved to the second position, avoiding collision interference between the second module 12 of the handle and the external instruments inserted into the instrument inlet / outlet connector 15 when the second module 12 of the handle is in the second position. More specifically, in Figure 8 and Figure 9 As an example, the first module 11 of the handle is equipped with a return fluid mechanism 50 that communicates with the insertion part 20. The return fluid mechanism 50 is connected to the inlet connector 13 via the inlet tube 51, the return fluid mechanism 50 is connected to the return fluid connector 14 via the return fluid tube 52, and the return fluid mechanism 50 is connected to the instrument inlet / outlet connector 15 via the instrument tube 53. It should be noted that since the communication method between the return fluid mechanism 50 and the insertion part 20 and the specific structure of the return fluid mechanism 50 are well known in the art, please refer to the hysteroscope and its return fluid mechanism disclosed in Chinese Patent Application No. 202421265388.3, ​​so they will not be described again here; in addition, the instrument inlet / outlet connector 15 refers to the insertion or withdrawal of external instruments into or out of the variable handle hysteroscope 100 of this utility model.

[0037] Compared with the prior art, since the handle 10 includes a first handle module 11 for mounting and connecting the tail end 21 of the insertion part 20 and a second handle module 12 movably mounted on the first handle module 11, the second handle module 12 can move relative to the first handle module 11 between a first position and a second position. Therefore, by moving the second handle module 12 between the first position and the second position, the shape of the handle 10 can be changed accordingly to meet different clinical operation needs, such as the needs of static observation operation and rotation operation.

[0038] It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims. Furthermore, the embodiments disclosed above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of this utility model. Therefore, equivalent variations made within the scope of the claims of this utility model are still within the scope of this utility model.
