Description

Technical Field

[0001] The utility model relates to the technical field of thyroid surgery, in particular to a parathyroid gland identification device. Background Art

[0002] Hypoparathyroidism is an important complication of thyroidectomy. Effective preservation of the parathyroid glands during surgery is particularly important, and accurate identification of the parathyroid glands during surgery is a prerequisite for effective preservation of the parathyroid glands.

[0003] In the prior art, the identification of parathyroid glands mainly relies on the naked eye of experienced doctors or the use of laser Raman spectroscopy detection technology. Raman probes are high-precision optical devices that are integrated with instruments and usually need to be in direct contact with the human body when used during surgery. Since the probe contains a circuit board structure, it is electrically connected to the instrument body and cannot be disassembled and disinfected. Therefore, cross infection is easily caused when performing surgery on different patients. Therefore, a parathyroid gland identification probe that can reduce the chance of cross infection is needed.

In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] A parathyroid gland identification device includes an identification probe and a protective cover. The identification probe includes a detection head 1, a grip 2 and a connecting line 3. The front end of the grip 2 is provided with the detection head 1, and the rear end is connected to the identification instrument body through the connecting line 3 (the identification instrument body is not shown in the figure). The grip 2 is formed with an installation cavity 15. The detection head 1 is a metal tube, and an optical fiber connected to the inside of the grip 2 is provided inside (not shown in the figure). Anti-skid rubber pads 16 are provided on both sides of the grip 2 along the middle mirror image.

[0023] The protective cover comprises a transparent protective film 4 and a mounting ring 5 , and the opening of the protective film 4 is sleeved and fixed on the mounting ring 5 .

[0024] The front end of the gripping handle 2 is formed with an annular mounting groove 6, the mounting ring 5 is movably sleeved on the mounting groove 6, and the protective film 4 is sleeved on the outside of the detection head 1. The mounting ring 5 is provided with a pair of clamping grooves 7. The front end of the gripping handle 2 is provided with a clamping block 8 at a position corresponding to each clamping groove 7. The clamping block 8 is retractably arranged and clamped on the inner side of the clamping groove 7. The gripping handle 2 is provided with a groove 9 for accommodating the clamping block 8 at a position corresponding to each clamping block 8. The clamping block 8 is connected and fixed to the inner side of the groove 9 through a spring 10. A slide groove 11 is provided on one side of the groove 9. A slider 12 is fixed on one side of the clamping block 8. The slider 12 is movably installed on the inner side of the slide groove 11. A pressing groove 13 that passes through to the outside is provided on the opposite sides of the two slide grooves 11. A pressing rod 14 is fixed on the non-fixed end of the slider 12. The pressing rod 14 is movably installed on the inner side of the pressing groove 13, and the non-fixed end of the pressing rod 14 extends to the outer side of the pressing groove 13. The cross section of the clamping block 8 is a right-angled trapezoid, and the inclined surface end of the clamping block 8 extends to the outside of the groove 9 and is clamped in the inside of the clamping groove 7 , and the inclined surface of the clamping block 8 faces the detection head 1 .

[0025] It is worth noting that the identification device body used in the present invention is an existing device, and the inside of the handle 2 is provided with a circuit board, a laser emitting part and an optical signal receiving part, which are all existing technologies.

[0026] When the utility model is implemented:

[0027] like Figure 1 and Figure 2 As shown, take out the disposable protective cover, and put the mounting ring 5 of the protective cover on the mounting groove 6, so that the transparent protective film 4 of the protective cover can be put on the detection head 1. In this process, Figure 4 As shown, the clamping block 8 can first squeeze the spring 10 to be retracted into the inside of the groove 9, and then enter the inside of the clamping groove 7 under the pushing action of the spring 10, so that the mounting ring 5 can be fixed on the gripping handle 2, and the identification probe can be used to identify the patient's parathyroid glands. The identification probe can emit laser, and the laser can pass through the transparent protective film 4, and the identification probe can receive the reflected light and transmit the optical signal to the instrument body for analysis, so as to realize the identification of the parathyroid glands. Through the above operation, it is possible to avoid direct contact between the identification probe and the patient's body parts during identification;

[0028] After use, the two pressing rods 14 are pressed to push the block 8 into the groove 9, thereby releasing the fixation of the mounting ring 5. The protective cover can be removed and discarded at this time. When the identification probe is used again, the above operation can be repeated to install a new disposable protective cover. By installing a disposable protective cover on the identification probe, the chance of cross infection can be reduced, thereby effectively protecting the patient's safety.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
