Description

Technical Field

[0001] This utility model relates to the field of confocal probe technology, and in particular to a lightweight confocal probe catheter. Background Technology

[0002] A confocal endoscopy system is a device used for clinical microscopic observation of the human body. It consists of a confocal main unit and a confocal probe. The confocal probe needs to be connected to the fiber optic coupler of the confocal main unit via a connector to complete the transmission of optical signals. The confocal probe connector consists of a handle, plug, grounding rod, fiber optic bundle, sleeve, and imaging objective lens.

[0003] Chinese invention patent CN110755019A discloses a confocal probe connector and confocal system with ID recognition function. By setting an ID chip, it solves the problem that the number of times or the duration of use of the probe cannot be obtained in a timely manner in the prior art.

[0004] When installing the ID chip, it is necessary to first insert the ID chip into the hole at the end of the connecting rod, and then fix the pins of the ID chip, which makes it inconvenient to install the ID chip. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight confocal probe guide that facilitates the installation of an ID chip.

[0006] The lightweight confocal probe catheter provided by this utility model adopts the following technical solution:

[0007] A lightweight confocal probe catheter, comprising:

[0008] A plug, including the opposite distal and proximal ends;

[0009] A handle is fitted onto the distal end of the plug, forming an installation space between the handle and the distal end of the plug:

[0010] An ID chip is located within the installation space.

[0011] Optionally, a limiting groove is provided on the plug within the installation space, and the ID chip is placed within the limiting groove.

[0012] Optionally, it also includes a positioning sleeve fitted onto the distal end of the plug, the handle being snapped onto the positioning sleeve, and an insulating gasket being provided between the plug and the positioning sleeve;

[0013] The ID chip has a first pin and a second pin. The first pin is electrically connected to the positioning sleeve, and the second pin is electrically connected to the plug.

[0014] Optionally, the handle includes a first housing and a second housing, which are detachably connected.

[0015] Optionally, a protruding rib is fixedly connected to the first outer shell, and a limiting groove is formed on the second outer shell, wherein the protruding rib is adapted to the limiting groove and can be inserted into the limiting groove.

[0016] Optionally, a support plate is further provided on the inner wall of the first outer shell and / or the second outer shell, and a hollow groove is formed on the support plate.

[0017] Optionally, the outer wall of the plug is provided with a first annular groove, and when the plug is inserted into the hollow groove, the support plate can be inserted into the first annular groove.

[0018] Optionally, the inner wall of the handle is fixed with a limiting ridge, and the outer wall of the positioning sleeve is provided with a second annular groove. The limiting ridge is adapted to the second annular groove and can be inserted into the second annular groove.

[0019] Optionally, a hand-held portion may be provided on the first housing and / or the second housing.

[0020] Optionally, the handheld portion is formed by a recess within the outer shell of the handle.

[0021] This invention first creates an installation space between the handle and the distal end of the plug. By setting up the installation space, the handle is hollow, which facilitates the installation of the ID chip. Furthermore, by disassembling the handle into a first shell and a second shell that are detachably connected to each other, the ID chip can be fixed to the distal end of the plug first, and then the first shell and the second shell can be fixed together to confine the ID chip within the installation space. This installation method further facilitates the installation of the ID chip and the fabrication of a lightweight confocal probe guide. Moreover, by setting a limiting groove, the ID chip is further confined, further reducing the shaking of the ID chip within the installation space.

[0022] Because an installation space is formed between the handle and the distal end of the plug, the handle is hollow, enabling lightweight manufacturing of the handle and thus lightweight confocal probe catheter, making it convenient for users to use. Attached Figure Description

Installation space. Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 The present invention will be further described in detail below.

[0030] A lightweight confocal probe catheter, as referenced Figure 1 It includes a plug 1, a handle 4 and an ID chip 5. The plug 1 includes a distal end and a proximal end. The handle 4 is sleeved on the distal end of the plug 1, and an installation space 10 is formed between the handle 4 and the distal end. The ID chip 5 is disposed in the installation space 10.

[0031] Furthermore, the handle 4 includes a first outer shell 41 and a second outer shell 42, which are detachably connected. When installing the ID chip 5, the ID chip 5 can be first fixed to the plug 1, and then the first outer shell 41 and the second outer shell 42 can be fixed to each other, thereby limiting the installation of the ID chip 5 within the installation space 10. In this embodiment, the first outer shell 41 and the second outer shell 42 are detachably connected by a snap-fit ​​6. In other embodiments, the first outer shell 41 and the second outer shell 42 can also be detachably connected by bolts or other means.

[0032] Reference Figure 2 and Figure 3 Furthermore, a handheld part 9 is provided on the first outer shell 41 and / or the second outer shell 42. In this embodiment, a handheld part 9 is provided on both the first outer shell 41 and the second outer shell 42. By providing the handheld part 9, it is convenient for the user to hold the confocal probe catheter.

[0033] Furthermore, the handhold 9 is recessed within the outer shell of the handle 4. Since the handhold 9 is recessed, it is easier to restrain the user's hand and reduce the occurrence of the handle 4 falling from the user's hand. In other embodiments, the handhold 9 can be convexly formed from the outer shell of the handle 4, and the convexity forms anti-slip textures, thereby reducing the occurrence of the handle 4 falling from the user's hand.

[0034] Reference Figure 4 and Figure 5 Furthermore, a positioning sleeve 3 is fitted onto the distal end of the plug 1, and the handle 4 is snapped onto the positioning sleeve 3. An insulating gasket 2 is provided between the positioning sleeve 3 and the plug 1. In this embodiment, the insulating gasket 2 is fixedly fitted onto the plug 1, and the positioning sleeve 3 is fixedly fitted onto the insulating gasket 2. The ID chip 5 is provided with a first pin 51 and a second pin 52. The first pin 51 is electrically connected to the positioning sleeve 3, and the second pin 52 is electrically connected to the plug 1. The positioning sleeve 3 is partially exposed outside the handle 4, and can be electrically connected to other devices during use, thereby realizing the electrical connection between other devices and the ID chip 5.

[0035] Specifically, a second annular groove 31 is formed on the positioning sleeve 3, and a limiting ridge 8 is fixedly connected to the inner wall of the handle 4. The limiting ridge 8 is inserted into the second annular groove 31 to achieve the snap-fit ​​between the handle 4 and the positioning sleeve 3. In this embodiment, the aforementioned limiting ridge 8 is fixed on the inner wall of both the first outer shell 41 and the inner wall of the second outer shell 42. The second annular groove 31 is arranged around the circumference of the positioning sleeve 3. Through the cooperation between the limiting ridge 8 on the first outer shell 41 and the second outer shell 42 and the second annular groove 31, the outer shell 4 and the plug 1 are fixedly connected.

[0036] When installing ID chip 5, firstly, the first pin 51 on ID chip 5 is soldered and fixed to the positioning sleeve 3, and the second pin 52 is soldered and fixed to the plug 1, thus completing the installation of ID chip 5. Then, the first outer shell 41 and the second outer shell 42 are snapped onto the positioning sleeve 3 through the limiting ridge 8, thus completing the installation of handle 4. At this time, an installation space 10 is formed between the plug 1 and the inner wall of handle 4, and ID chip 5 is confined within the installation space 10, reducing the interference of external factors on ID chip 5.

[0037] Furthermore, a limiting groove 11 is provided on the plug 1 in the installation space 10. The ID chip 5 is placed in the limiting groove 11. The limiting groove 11 limits the ID chip 5, reducing the possibility of the ID chip 5 shaking due to the shaking of the handle 4 during the use of the confocal probe guide, which could cause the first pin 51 and / or the second pin 52 to bend, thereby reducing the possibility of the first pin 51 and / or the second pin 52 breaking.

[0038] Furthermore, a protruding rib 411 is fixedly connected to the end face of the first outer shell 41 near the second outer shell 42, and a limiting groove 421 corresponding to the protruding rib 411 is formed on the end face of the second outer shell 42 near the first outer shell 41. Before the first outer shell 41 and the second outer shell 42 are fixed together by the snap fastener 6, the protruding rib 411 is first inserted into the corresponding limiting groove 421 to initially limit the position between the first outer shell 41 and the second outer shell 42. After the protruding rib 411 is inserted into the limiting groove 421, the first outer shell 41 and the second outer shell 42 are brought into contact with each other, thereby fixing the first outer shell 41 and the second outer shell 42 together by the snap fastener 6, realizing the fixed installation between the first outer shell 41 and the second outer shell 42. Due to the addition of the protruding rib 411 and the limiting groove 421, the connection stability between the first outer shell 41 and the second outer shell 42 is increased.

[0039] Furthermore, a support plate 7 is provided on the inner wall of the first outer shell 41 and / or the second outer shell 42, and a hollow groove 71 is provided on the support plate 7.

[0040] In one embodiment, the support plate 7 cooperates with the plug 1 to support the plug 1. Specifically, support plates 7 are fixedly installed on the inner walls of both the first outer shell 41 and the second outer shell 42. A hollow groove 71 is provided in the support plate 7, which is adapted to the plug 1. When the first outer shell 41 and the second outer shell 42 cooperate, the plug 1 passes through the hollow groove 71. Furthermore, a first annular groove 12 is provided on the plug 1 within the installation space 10. When the plug 1 is inserted into the slot, the support plate 7 engages with the first annular groove 12, thereby restricting the movement of the plug 1 along its own axis and further increasing the connection stability between the plug 1 and the handle 4.

[0041] In another embodiment, the support plate 7 serves as a reinforcing rib in the handle 4, strengthening the outer shell of the handle 4. Specifically, a support plate 7 is fixedly installed on the inner wall of both the first outer shell 41 and the inner wall of the second outer shell 42. A hollow groove 71 is provided in the support plate 7, through which an optical fiber passes.
