Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a hysteroscope and an insertion part thereof. Background Art

[0002] As we all know, the hysteroscope is a minimally invasive gynecological diagnostic and treatment instrument used to diagnose, treat, and follow up intrauterine lesions. It not only determines the location, size, appearance, and extent of lesions, but also allows for detailed observation of the tissue structure on the surface of the lesions and direct visualization for sampling or positioning for curettage. This significantly improves the accuracy of diagnosing intrauterine diseases, updating, developing, and addressing the shortcomings of traditional diagnostic and treatment methods. For most patients suitable for diagnostic curettage, it is more reasonable and effective to first perform a hysteroscopy to determine the location of the lesion and then proceed with a biopsy or curettage.

[0003] Among them, for the integrated transfer liquid connector and endoscope system disclosed in Chinese patent application No. 202310264024.7, since its insertion part is a hard tube structure, a corresponding rotation structure is configured. The insertion part can be rotated by rotating the rotation structure, thereby driving the camera device to rotate to obtain different fields of view.

[0004] However, since the insertion portion is a rigid tube structure, doctors cannot pre-bend the insertion portion to a desired shape and angle according to actual needs.

[0005] Therefore, there is an urgent need for a hysteroscope and an insertion portion thereof to overcome one or more of the above-mentioned defects. Utility Model Content

The rigid tube head end of the universal tube is assembled and connected to the tip, and the instrument tube is located within the universal tube. The head end of the instrument tube also passes through the rigid tube head end of the universal tube and extends into the tip.

[0009] Compared with the existing technology, the utility model adopts the design that "the universal tube includes a hard tube head end, a bendable shaping section and a hard tube tail end connected in sequence along its length direction, the hard tube head end of the universal tube is assembled and connected with the front end, the instrument tube is located in the universal tube, and the head end of the instrument tube also passes through the hard tube head end of the universal tube and extends into the front end." Therefore, the insertion part of the utility model can bend the bendable shaping section according to actual needs, so that the insertion part of the utility model is pre-bent to the desired angle and shape, and can maintain the pre-bent shape, thereby facilitating the doctor's use and operation. In addition, because the desired angle is achieved by operating the bendable shaping section, the rotation function of the insertion part of the traditional hysteroscope can be eliminated, making operation more convenient.

[0010] Preferably, the universal tube is a metal universal tube.

[0011] Preferably, the tail end of the instrument tube also passes through the tail end of the hard tube of the universal tube, and the instrument tube defines a return channel in the internal space of the universal tube.

[0026] See also Figure 1 The hysteroscope 100 of the present invention includes an insertion portion 10 and a handle 20. Since the structure of the handle 20 is well known in the art and the handle 20 is not an improvement of the present application, it will not be described in detail here.

[0027] Recombination Figure 2 and Figure 4 The insertion portion 10 includes a tip 11, a long instrument tube 12, and a long, bendable and shaped universal tube 13. The universal tube 13 includes a hard tube head 13a, a bendable and shaped section 13b, and a hard tube tail 13c, which are connected in sequence along its length. The hard tube head 13a of the universal tube 13 is assembled and connected to the tip 11, so that the hard tube head 13a of the universal tube 13 and the tip 11 are fixed together; the hard tube tail 13c of the universal tube 13 is assembled on the handle 20, and the handle 20 provides support for the universal tube 13. The state is shown in FIG. Figure 4 As shown. The instrument tube 12 is located in the universal tube 13, and the universal tube 13 surrounds the instrument tube 12 from the periphery; the head end 121 of the instrument tube 12 also passes through the hard tube head end 13a of the universal tube 13 and extends into the front end 11, the state is shown Figure 4 Specifically, Figure 4As an example, the tail end 122 of the instrument tube 12 also passes through the hard tube tail end 132 of the universal tube 13, so that the tail end 122 of the instrument tube 12 is exposed to the outside from the side of the handle 20, thereby facilitating the operation of external instruments and tools entering the instrument tube 12 from the tail end 122 of the instrument tube 12; and the instrument tube 12 defines a return channel 133 in the internal space of the universal tube 13, and a return port 132 is opened on the side wall 131 of the hard tube head end 13a of the universal tube 13, and the front end 11 closes the head end 1331 of the return channel 133, and the front end 11 also opens an inner portion of the head end 121 of the instrument tube 12. The space 1211 is connected to the docking channel 111; this design allows the water inlet and return water of the hysteroscope 100 of the present invention to be separated from each other. For example, water can be taken in by means of the instrument tube 12, and then the water taken in by the instrument tube 12 is discharged through the docking channel 111 of the front end 11, and then the water is returned by means of the return water port 132 on the side wall 13 of the hard tube head end 13a, so that the returned water is returned through the return water channel 133; therefore, water is discharged from the end of the front end 11 and returned to the side of the hard tube head end 13a of the universal tube 13, thereby effectively reducing the interference between the water outlet and the return water, thereby improving the utilization efficiency of the cleaning water and enhancing the cleaning effect. More specifically, as follows:

[0028] like Figures 1 to 4 As shown, as an example, the insertion portion 10 further includes an outer sleeve 14 that is sleeved on the universal tube 13. The head end 141 and the tail end 142 of the outer sleeve 14 both protrude from the bendable shaping section 13b, so that the outer sleeve 14 completely covers the bendable shaping section 13b, thereby improving the smoothness of the insertion portion 10 during the insertion or removal process. Figure 4 In one example, the head end 141 of the outer sleeve 14 seals with the hard tube head end 13a of the universal tube 13 to prevent leakage at the joint between the head end 141 and the hard tube head end 13a of the universal tube 13. The tail end 142 of the outer sleeve 14 seals with the hard tube tail end 13c of the universal tube 13 to prevent leakage at the joint between the tail end 142 and the hard tube tail end 13c of the universal tube 13. For example, the universal tube 13 is a metal universal tube to improve its strength. Alternatively, the outer sleeve 14 is a rubber sleeve to improve the flexibility of the outer sleeve 14 and enhance the comfort of the insertion portion 10 when in contact with the outside world. Furthermore, the instrument tube 12 is a hose, for example, a plastic hose with a spring coil, which facilitates the insertion and removal of external instruments and tools. Optionally, the instrument tube 12 is a clamp tube to facilitate the insertion and removal of forceps.

[0029] Compared with the prior art, the invention adopts the design that "the universal tube 13 includes a hard tube head end 13a, a bendable shaping section 13b and a hard tube tail end 13c connected in sequence along its length direction, the hard tube head end 13a of the universal tube 13 is assembled and connected with the front end 11, the instrument tube 12 is located in the universal tube 13, and the head end 121 of the instrument tube 12 also passes through the hard tube head end 13a of the universal tube 13 and extends into the front end 11". Therefore, the insertion part 10 can be bent to the bendable shaping section 13b according to actual needs, so that the insertion part 10 is pre-bent to the desired angle and shape, and can maintain the pre-bent shape, thereby facilitating the doctor's use and operation of the hysteroscope 100 of the present invention. In addition, since the desired angle is achieved by operating the bendable shaping section 13b, the rotation function of the insertion part of the traditional hysteroscope can be eliminated, so the operation of the hysteroscope 100 of the present invention is more convenient.

[0030] It should be noted that the direction indicated by arrow A and the opposite direction in the drawings are the length directions of the universal tube 13. In addition, the specific structure of the bendable shaping section 13b of the universal tube 13 is well known in the art and will not be described in detail here.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved. At the same time, what is disclosed above is only the preferred embodiment of the present invention, and of course it cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
