Description

TECHNICAL FIELD

[0002] Medical catheters are important devices for minimally invasive interventional treatment. In the process of manufacturing medical catheters, different materials or outer diameters of tube bodies need to be spliced or combined, and a heat shrink tube is nested on the outer surface of the tube body to heat fuse the tube body. After heat fusion, the heat shrink tube needs to be removed from the tube body.

[0045] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the present application will be further described below in conjunction with the drawings and through specific embodiments.

[0046] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] ​​In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature can include that the first and second features are in direct contact, or can include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher than the second feature in horizontal height. The first feature "under", "below" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower than the second feature in horizontal height.

[0048] In the description of the present embodiment, the terms "upper", "lower", "left", "right" and other orientation or position relationships shown in the drawings are based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used to distinguish in the description, and have no special meaning.

[0049] The conventional heat shrink tube stripping device usually opens a dovetail groove on the pipe clamping seat to clamp the heat shrink tube, so as to realize the clamping and positioning of the heat shrink tube. When the clamping is too tight, the inner tube of the heat shrink tube is easily damaged. When the clamping is too loose, the heat shrink tube is easily radially offset and jumps in the dovetail groove. When the stripping knife feeds and strips, the tube is easily damaged, which greatly reduces the stripping precision of the heat shrink tube.

[0050] In order to solve the above problems, such as Figure 1 and Figure 2As shown, the embodiment provides a heat shrink tube stripping device which can assist manual stripping of the heat shrink tube. The heat shrink tube stripping device comprises a mounting assembly 1, a stripping knife assembly 2 and a distance adjusting assembly 3. The mounting assembly 1 comprises a mounting base 11 and a mounting sleeve 12 connected together. The heat shrink tube to be stripped is movably arranged in the mounting sleeve 12 along the axial direction (front-rear direction in the figure). An exposed groove 121 is formed on the wall of the mounting sleeve 12. The stripping knife assembly 2 is slidably connected to the mounting base 11 and is arranged opposite to the exposed groove 121. The distance adjusting assembly 3 can adjust the movement of the stripping knife assembly 2 towards the exposed groove 121 so that the stripping knife assembly 2 cuts into the outer wall of the heat shrink tube to be stripped through the exposed groove 121. The heat shrink tube stripping device drives the stripping knife assembly 2 to feed through the distance adjusting assembly 3 and accommodates and positions the heat shrink tube to be stripped through the mounting sleeve 12, which avoids radial deviation and jumping of the heat shrink tube to be stripped and ensures accurate stripping of the heat shrink tube to be stripped by the stripping knife assembly 2, avoids damage to the inner tube of the heat shrink tube to be stripped by the stripping knife assembly 2 and improves the stripping accuracy of the heat shrink tube to be stripped.

[0051] In the embodiment, the mounting base 11 comprises a bottom plate 111, a pressing strip 112 and a mounting plate 113. The bottom plate 111 is slidably connected to the stripping knife assembly 2. The mounting plate 113 is detachably connected to the bottom plate 111. The pressing strip 112 is detachably connected to the mounting plate 113. The pressing strip 112 and the mounting plate 113 are assembled together to form a clamping hole 114 for clamping and fixing the mounting sleeve 12 in the clamping hole 114. The mounting sleeve 12 is clamped and fixed by the pressing strip 112 and the mounting plate 113, which ensures the stability of the clamping of the mounting sleeve 12. In addition, when it is necessary to replace the mounting sleeve 12 of different diameters to accommodate the heat shrink tube to be stripped, the appropriate size of the pressing strip 112 and the mounting plate 113 can be replaced to assemble the clamping hole 114 of the appropriate size to clamp the mounting sleeve 12, without the need to replace the entire heat shrink tube stripping device, which greatly improves the applicability of the heat shrink tube stripping device. It should be noted that the mounting plate 113 can be fixedly connected to the bottom plate 111 by bolts. The pressing strip 112 can also be fixedly connected to the mounting plate 113 by bolts. The bolts are connected to realize detachable installation and also ensure the stability and reliability of the connection.

[0052] Preferably, in the present embodiment, the leading end and the trailing end of the heat shrink tube to be stripped extend out of the mounting sleeve 12. When the stripping knife assembly 2 is fed into position, the operator can easily pull the heat shrink tube to be stripped relative to the mounting sleeve 12 in the front-rear direction by holding the leading end or the trailing end of the heat shrink tube to be stripped, thereby achieving the stripping operation of the heat shrink tube to be stripped. Further, in the present embodiment, the length of the leading end and the trailing end of the heat shrink tube to be stripped extending out of the mounting sleeve 12 is 30-50 mm, thereby facilitating the holding of the heat shrink tube to be stripped. It should be noted that the outer peripheral wall of the heat shrink tube to be stripped is in abutment with the inner peripheral wall of the mounting sleeve 12, thereby achieving the limiting of the heat shrink tube to be stripped in the radial direction and ensuring that the heat shrink tube to be stripped can only move relative to the mounting sleeve 12 in the axial direction under the action of an external force.

[0053] Preferably, in the present embodiment, the distance adjusting assembly 3 comprises a fixed base 31 and a differential head 32, wherein the fixed base 31 is mounted on the bottom plate 111, and the measuring rod of the differential head 32 is screwed through the fixed base 31 and abuts against the stripping knife assembly 2. By screwing the differential head 32, the stripping knife assembly 2 can be driven to move relative to the fixed base 31 towards the exposed groove 121. By adjusting the feed depth of the stripping knife assembly 2 through the differential head 32, the feed distance of the stripping knife assembly 2 can be more intuitively observed, thereby accurately controlling the depth of the stripping knife assembly 2 cutting into the outer tube wall of the heat shrink tube to be stripped, preventing the internal tube body from being damaged during stripping, and ensuring the accuracy of the stripping operation. Since the specific structure and working principle of the differential head 32 belong to the prior art, they will not be described here.

[0054] In addition, the heat shrink tube stripping device provided in the present embodiment further comprises an elastic reset assembly (not shown in the figure), which is clamped between the mounting plate 113 and the stripping knife assembly 2 and is used to drive the stripping knife assembly 2 to move and reset in the direction away from the exposed groove 121. Specifically, the elastic reset assembly can be a spring. When the differential head 32 is forwardly screwed to adjust the feed of the stripping knife assembly 2, the spring is further compressed at this time. When the differential head 32 is reversely screwed to move the measuring rod in the direction away from the exposed groove 121, the stripping knife assembly 2 moves in the direction away from the exposed groove 121 under the action of the elastic restoring force of the spring and always abuts against the measuring rod of the differential head 32. The spring has the advantages of good elastic effect and easy installation.

[0055] In combination with Figure 1 and Figure 2 The specific structure of the stripping knife assembly 2 will be described as follows. Figure 1 and Figure 2As shown, the stripping knife assembly 2 comprises a knife mounting seat 21 and a stripping knife 22, wherein the knife mounting seat 21 is in sliding connection with the bottom plate 111, the stripping knife 22 is detachably mounted on the knife mounting seat 21, and the stripping knife 22 can cut into the outer tube wall of the heat shrink tube to be stripped through the exposed slot 121. When it is necessary to replace the stripping knife 22, the old stripping knife 22 can be detached from the knife mounting seat 21, and then a new stripping knife 22 is replaced.

[0056] Preferably, in the present embodiment, the knife head of the stripping knife 22 is in the shape of a circular arc, and the exposed slot 121 is also in the shape of a circular arc, which is matched with the shape of the knife head. By designing the knife head of the stripping knife 22 in the shape of a circular arc, the reliability of the stripping operation is further ensured.

[0057] In order to ensure the reliability and stability of the feeding movement of the stripping knife 22, as shown in the drawings, Figure 2 As shown, the bottom plate 111 is provided with a guide rail 1111 extending in the direction (left-right direction in the drawings) in which the stripping knife assembly 2 approaches or moves away from the exposed slot 121, and the knife mounting seat 21 is provided with a sliding block 211 in sliding connection with the guide rail 1111. By providing the guide rail 1111 and the sliding block 211, a guiding effect is provided for the feeding movement of the stripping knife 22, so as to ensure that the stripping knife 22 is accurately and directly opposite to the exposed slot 121, and to ensure that the stripping knife 22 more reliably cuts into the outer tube wall of the heat shrink tube to be stripped.

[0058] In addition, as shown in the drawings, Figure 2 The heat shrink tube stripping device provided by the present embodiment further comprises a locking assembly 4 for locking the stripping knife assembly 2 and the mounting base 11 with the adjusted relative position. By providing the locking assembly 4, the relative position between the stripping knife 22 and the heat shrink tube to be stripped is stably fixed, and the reliability of the stripping operation is further ensured.

[0059] Specifically, the locking assembly 4 comprises a locking screw 41, a long slot 2111 is formed in the sliding block 211 of the knife mounting seat 21, the long slot 2111 extends in the direction (left-right direction in the drawings) in which the stripping knife assembly 2 approaches or moves away from the exposed slot 121, and the locking screw 41 is in threaded connection with the guide rail 1111 on the bottom plate 111 after passing through the long slot 2111. When it is necessary to adjust the position of the stripping knife assembly 2, the locking screw 41 is loosened, and then the locking screw 41 slides along the long slot 2111 following the stripping knife assembly 2, and the locking screw 41 is tightened after the relative position between the stripping knife assembly 2 and the mounting base 11 is adjusted. By providing the locking screw 41, the locking of the stripping knife assembly 2 and the mounting base 11 is realized, the connection is more reliable, and the operation is also facilitated.

[0060] Preferably, the locking assembly 4 further comprises a screw head 42 connected with the free end of the locking screw 41. By arranging the screw head 42, the screwing operation of the locking screw 41 is facilitated.

[0061] Preferably, in the present embodiment, as shown in Figure 3 both sides of the mounting sleeve 12 in the radial direction (left-right direction in the figure) are provided with a stripping knife assembly 2, each of which is arranged opposite to an exposed slot 121 on the wall of the mounting sleeve 12, and the two stripping knife assemblies 2 can jointly feed and cut into the outer wall of the heat-shrinkable tube to be stripped at the corresponding position. When the heat-shrinkable tube to be stripped is pulled to move relative to the mounting sleeve 12 in the front-back direction, the outer walls of the heat-shrinkable tube to be stripped on both sides in the left-right direction are divided, improving the stripping effect on the heat-shrinkable tube to be stripped. It should be noted that the two stripping knife assemblies 2 do not need to be arranged opposite to each other in the left-right direction, but only need to be arranged opposite to the exposed slots 121 on the corresponding side.

[0062] As shown in ​ the present embodiment further provides a heat-shrinkable tube stripping method applied to the heat-shrinkable tube stripping device described above, which comprises the following steps:

[0063] After the heat-shrinkable tube stripping device is assembled, the heat-shrinkable tube to be stripped is arranged in the mounting sleeve 12;

[0064] The distance adjusting assembly 3 is used to adjust the stripping knife assembly 2 to move towards the exposed slot 121, and the stripping knife assembly 2 cuts into the outer wall of the heat-shrinkable tube to be stripped through the exposed slot 121;

[0065] The heat-shrinkable tube to be stripped is pulled to move relative to the mounting sleeve 12 in the axial direction.

[0066] The heat-shrinkable tube stripping method provided by the present embodiment drives the stripping knife assembly 2 to feed through the distance adjusting assembly 3, and positions the heat-shrinkable tube to be stripped through the mounting sleeve 12. When the heat-shrinkable tube to be stripped is pulled to move relative to the mounting sleeve 12 in the axial direction, the heat-shrinkable tube to be stripped is prevented from being offset and jumping in the radial direction, ensuring the accurate stripping of the heat-shrinkable tube to be stripped by the stripping knife assembly 2 and improving the stripping precision of the heat-shrinkable tube to be stripped.

[0067] It should be noted that when the heat-shrinkable tube stripping device is assembled, a mounting plate 113 of appropriate size is first mounted on the base plate 111, then a mounting sleeve 12 of appropriate inner diameter is selected, and finally a pressing strip 112 of corresponding size is used to clamp and fix the mounting sleeve 12 in the clamping hole 114.

[0068] It should be noted that when the heat shrink tube stripping device is processed, first, the exposed groove 121 is milled on the pipe wall of the mounting sleeve 12 by a milling machine, then the slide block 211 on the blade mounting seat 21 is processed by a numerical control machine tool, and finally the entire device needs to be surface sand blasted.

[0069] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation manners of the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the implementation manners are not required or can not be exhausted. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
