Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a cavity stripper for prosthetic breast augmentation. Background Art

[0002] Breast augmentation with implants is a common surgical procedure in plastic surgery. The posterior pectoralis major space is a common surgical plane. By separating a space behind the pectoralis major muscle and inserting the implant, the breast volume can be significantly increased, thereby achieving the effect of breast elevation and lifting. Usually, when doctors perform stripping of the posterior pectoralis major space, they use their fingers for blunt stripping of the shallower part, and use a stripping spatula for the deeper part.

[0003] Common stripping spatulas are mostly handheld structures, such as I-shaped, L-shaped, and U-shaped stripping spatulas, one end of which is a sheet-shaped stripping head. During the stripping process, the operator generally directly pushes the stripping spatula to move as a whole. Since the size of the cavity space exceeds the preoperative design range or is insufficient, it will affect the subsequent implantation effect of the prosthesis. The size of the stripping cavity needs to be accurately controlled, which makes the above operation method require a high control of the operating force of the stripping spatula. At the same time, there is also a risk of forced stripping and breast tissue damage due to errors in the control of the operating force. Utility Model Content

[0004] The purpose of the utility model is to provide a cavity stripper for breast augmentation with prosthesis, which can improve the operator's control over the situation of the cavity stripping area and the size of the cavity stripping space, thereby ensuring the efficiency of the cavity stripping operation.

[0005] The technical solution adopted by the utility model to solve the above problems is:

[0006] A cavity stripper for breast augmentation with implants, comprising:

[0007] handle;

[0008] An extension rod, the inner end of which is slidably disposed on the handle along the central axis of the handle and cannot rotate, and a shovel blade is disposed on the outer end of the extension rod;

[0009] Among them, the handle is rotatably connected to a driving sleeve. When the driving sleeve rotates relative to the handle, the driving sleeve drives the extension rod to slide relative to the handle through a transmission mechanism. The handle and the extension rod are respectively penetrated by a first channel and a second channel along their axial direction. The first channel and the second channel are connected to form an accommodating channel for the endoscope to pass through.

[0010] As a further improvement of the above technical solution, the handle includes a main body and a shell, the extension rod is slidably connected to the main body, the transmission mechanism is located on the main body, the main body is inserted into the driving sleeve, the shell is sleeved on the lower part of the driving sleeve, the bottom ends of the main body and the shell are connected by a snap-fit ​​structure, and the lower part of the driving sleeve is rotatably arranged in the interval space between the main body and the shell.

[0011] As a further improvement of the above technical solution, the transmission mechanism includes a threaded rod, which is rotatably connected to the cavity of the handle, and the inner end of the extension rod is sleeved on the threaded rod in a threaded manner. A gear ring is provided on the driving sleeve, and the gear ring is connected to the threaded rod through a gear transmission mechanism.

[0012] As a further improvement of the above technical solution, a spring clip for clamping an endoscope is provided at the outer end of the second channel.

[0013] As a further improvement of the above technical solution, a plurality of strip-shaped textures are provided on the outer surface of the driving sleeve at equal intervals along its circumferential direction.

[0014] As a further improvement of the above technical solution, the extension rod is provided with a length scale line, and the top of the main body is in a frustum shape.

[0015] As a further improvement of the above technical solution, a plurality of grooves are provided on the outer surface of the shell, the grooves are in a hemispherical shape and are arranged in a staggered lattice.

[0016] As a further improvement of the above technical solution, the outer end of the extension rod and the edge of the shovel blade are both provided with a chamfer structure.

[0017] Compared with the prior art, the utility model has the following advantages and effects:

[0018] (1) The utility model uses the movable arrangement between the handle and the extension rod, combined with the assembly structure of the endoscope on the stripper, to enable the operator to perform rapid cavity stripping (i.e., conventionally, stripping by directly pushing the stripper to drive the blade) and slow stripping (i.e., stripping by rotating the drive sleeve to drive the blade to slowly advance), based on the acquisition of breast tissue images of the area to be stripped. This improves the accuracy of the operator's stripping operation while reducing the requirement on the operator's operating force, and also improves the operator's control over the size of the cavity stripping space.

[0019] (2) The utility model can obtain images of the stripping operation area through an endoscope during the operation, thereby improving the operator's control over the situation in the cavity stripping area, thereby ensuring the efficiency of the cavity stripping operation. In addition, during the stripping operation, the operator can also promptly discover sudden situations in the cavity and deal with them (for example, after discovering the bleeding location, use an electrocoagulation hook or an ultrasonic knife to stop bleeding to avoid bleeding in the cavity that affects the operation field of view), thereby ensuring the normal progress of the operation.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0026] See also Figure 1-Figure 4 The present embodiment is a cavity stripper for breast augmentation with a prosthesis, comprising a handle 1 and an extension rod 2. The inner end of the extension rod 2 is slidably arranged on the handle 1 along the central axis of the handle 1 and cannot rotate. A shovel blade 3 is arranged on the outer end of the extension rod 2. A driving sleeve 4 is rotatably connected to the handle 1. When the driving sleeve 4 rotates relative to the handle 1, the driving sleeve 4 drives the extension rod 2 to slide relative to the handle 1 through a transmission mechanism 5. The handle 1 and the extension rod 2 are respectively penetrated by a first channel 61 and a second channel 62 along their axial directions. The first channel 61 and the second channel 62 are connected to form a receiving channel 63 for the endoscope to pass through.

[0027] When the handheld stripper is used, the endoscope installed on the stripper is used to obtain the breast tissue image of the area to be stripped just in front of the shovel blade 3, so that according to the looseness of the breast tissue in the image, the stripper can be directly pushed as a whole to perform rapid stripping, or the driving sleeve 4 can be rotated to drive the extension rod 2 to extend and drive the shovel blade 3 to perform slow stripping. While improving the operational flexibility, it also reduces the operational requirements for the operator's stripping force. During the operation, the operator can form a larger cavity by rapid stripping, and then perform a stripping operation on the edge of the formed cavity by slow stripping to achieve the expansion of a smaller space, thereby improving the control over the size of the stripped cavity space and ensuring the effect of implanting the prosthesis in the cavity.

[0028] In this embodiment, the extension rod 2 and the shovel blade 3 are both made of stainless steel.

[0029] See also Figure 1 The outer surface of the driving sleeve 4 is provided with a plurality of strip textures 41 at equal intervals along its circumference, which is beneficial to increase the friction between the finger and the driving sleeve 4, thereby ensuring the effectiveness of the finger pushing the driving sleeve 4 to rotate relative to the handle 1 during use.

[0030] See also Figure 1 , Figure 3 The handle 1 includes a main body 11 and a shell 12, the extension rod 2 is slidably connected to the main body 11, the transmission mechanism 5 is located on the main body 11, the main body 11 is inserted into the driving sleeve 4, the shell 12 is sleeved on the lower part of the driving sleeve 4, the bottom ends of the main body 11 and the shell 12 are connected by a snap structure 13, and the lower part of the driving sleeve 4 is rotatably arranged in the interval 14 between the main body 11 and the shell 12. Through the assembled structure of the handle 1, the convenience of assembling the various components in the handle 1 is improved, and the difficulty of mold manufacturing of the handle 1 is reduced, and each component can be manufactured separately, thereby reducing the loss of production and manufacturing.

[0031] See also Figure 1 The extension rod 2 is provided with a length scale line 21, which is conducive to improving the operator's control over the extension length of the extension rod 2. The top of the main body 11 is in a frustum shape 15, which reduces the visual obstruction and facilitates the operator to check the scale on the extension rod 2.

[0032] See also Figure 2 The outer end of the extension rod 2 and the edge of the shovel blade 3 are both provided with a chamfered structure 7, which reduces the thickness of the edge of the shovel blade 3, so that the shovel blade 3 can better extend between the tissues to be peeled off, and reduces the damage caused to the breast tissue by the edges of the extension rod 2 and the shovel blade 3 during the peeling process.

[0033] See also Figure 1 , Figure 3A plurality of grooves 16 are provided on the outer surface of the shell 12. The grooves 16 are hemispherical and arranged in a staggered array. This improves the visual effect of the handle 1 and increases the roughness of the surface of the handle 1, thereby ensuring the holding strength of the stripper.

[0034] See also Figure 3 The transmission mechanism 5 includes a threaded rod 51, which is rotatably connected to the cavity of the handle 1. The inner end of the extension rod 2 is sleeved on the threaded rod 51 in a threaded matching manner. The drive sleeve 4 is provided with a gear ring 52, which is connected to the threaded rod 51 through a gear transmission mechanism 53. The gear ring 52 is driven to rotate by rotating the drive sleeve 4, and the gear transmission mechanism 53 drives the threaded rod 51 to rotate, thereby driving the extension rod 2 to slide relative to the handle 1, so as to adjust the use length of the stripper before use and control the movement of the shovel blade 3 during the stripping process, thereby reducing the risk of breast tissue damage caused by directly pushing the stripper to perform cavity stripping.

[0035] See also Figure 4 The outer end of the second channel 62 is provided with a spring clip 8 for clamping the endoscope, so that when the endoscope is located in the accommodating channel 63, it can be clamped between the spring clip 8 and the extension rod 2 by the spring clip 8, so that when the extension rod 2 slides relative to the handle 1, it can drive the endoscope to move together, reducing the operation of adjusting the length of the endoscope in the stripper and improving the convenience of use.
