Embodiment 2

[0087] The difference from Example 1 is:

[0088] In this example, if Figure 3a-3d As shown, the first dimension hole 21 is a through hole, and the second dimension hole 22 is an axial blind hole.

[0089] In this example, if Figure 3a-3d As shown, when the second size hole 22 is an axial blind hole, when the tool assembly 4 drives the intermediate connecting piece 3 to pass through and connect to the radial matching area 2, the first guide piece 43 The distal end passes through the first size hole 21 and reaches the proximal end of the second size hole 22; wherein, the axial length L of the first guide member 43 01 , the axial length L of the first dimension hole 21 02 , the axial length L of the second guide 33 03 , the axial length L of the second dimension hole 22 04 , the axial length L of the limiting member 32 05 Satisfy the mathematical relationship: L 01 + L 03 ≤ L 04 , L 05 02 .

[0090] In this example, if Figure 3e As shown, the rotating operation pa...

Embodiment 3

[0092] The difference from Example 1 is:

[0093] In this example, if Figure 6a~6b and Figure 7a~7c As shown, a rapidly repeatable dismountable implant instrument 1 and its tool assembly 4 include, implant instrument 1, tool assembly 4 for repeated disassembly and assembly of the implant instrument 1, and the implant instrument 1 It includes a first assembly 11, a second assembly 12, an intermediate assembly 13, and an intermediate connector 3; between the first assembly 11 and the intermediate assembly 13, between the second assembly 12 and the intermediate assembly 13, there are Cooperating circumferential limiting structure; the first assembly 11 and the intermediate assembly 13, the second assembly 12 and the intermediate assembly 13 all form a mutual cooperative lateral connection structure with the intermediate connecting piece 3 , the circumferential limiting structure and the lateral connecting structure are all detachable connecting structures; wherein, the circum...

Abstract

The invention relates to the field of medical instruments, in particular to an implantation instrument and a handling tool assembly thereof, and the implantation instrument comprises a first assembly, a second assembly and a lateral connecting structure; circumferential limiting structures are arranged on the first assembly and the second assembly; the lateral connecting structure is used for axially limiting the first assembly and the second assembly. The loading and unloading tool assembly sequentially comprises a rotating operation part, a rotating force transmission piece and a first guide piece from the right end to the left end. According to the implanting instrument and the assembling and disassembling tool assembly thereof, free combination and repeated assembling and disassembling of parts of various specifications can be achieved according to actual requirements of patients, misoperation of doctors can be avoided, and compared with similar products in the market, the implanting instrument and the assembling and disassembling tool assembly thereof are better in safety, higher in convenience, wider in axial distance adjusting range and higher in flexibility.

Description

[0001] The invention belongs to the field of medical instruments, and in particular relates to an implant instrument and its loading and unloading tool assembly. Background technique [0002] At present, the existing medical interventional products include one-piece structure and split-type structure. For one-piece structure, the components of the product adopt axial cooperation, and the axial cooperation is when the implanted device is inserted into the sheath, rotated, and the steel cable is released in the opposite direction. Loosening is easy to occur during the process, which increases the risk of surgery. In addition, repeated disassembly and individual adjustment cannot be effectively realized during the matching process of various components of the product. The anti-loosening structures adopted are all realized through local deformation or displacement. The degree of damage to the device is uncontrollable, causing the product to lose its original shape, and due to the s...
