Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically, it relates to an auxiliary frame for creating a cavity in endoscopic breast surgery. Background Technology

[0002] There is no natural cavity in endoscopic breast surgery. During the operation, artificial cavities are mainly created by external skin suspension and internal air inflation. External skin suspension pulls on the skin surface, which is not only uneven but also easily causes skin flap necrosis. Internal air inflation pressure is difficult to control and may cause postoperative acidosis complications. To address this, we designed an auxiliary stent that mechanically supports an operating cavity during the operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an auxiliary frame for cavity creation in endoscopic breast surgery. The basic concept of the technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows:

[0004] An auxiliary frame for creating a cavity in laparoscopic breast surgery includes a sliding sleeve, a fixing sleeve, several support rods and diagonal rods, and a handle. The fixing sleeve, sliding sleeve, and handle are sequentially fitted onto the outer wall of the endoscope sheath. The fixing sleeve is detachably installed at the front end of the endoscope sheath. The sliding sleeve and the handle are slidably connected to the endoscope sheath. One end of each support rod is hinged to the sliding sleeve, and the other end extends outward from the front end of the endoscope sheath. Several support rods are evenly distributed along the circumference of the sliding sleeve and connected to it. One end of each diagonal rod is hinged to the fixing sleeve, and the other end is hinged to the non-endpoint of the support rod. One diagonal rod is provided for each support rod. The handle is connected to the sliding sleeve via a connecting rod.

[0005] Furthermore, the length ratio of the diagonal rod to the support rod is 1:2 to 1:4.

[0006] Furthermore, the diagonal rod is connected to the support rod at 1 / 2 axial length to 1 / 3 axial length near the sliding sleeve.

[0007] Furthermore, the free end of the support rod is spherical or teardrop-shaped.

[0008] Furthermore, there are five support rods and five diagonal rods.

[0009] Furthermore, the support rod, diagonal rod, sliding sleeve, fixing sleeve, pull rod, and handle glove are all made of stainless steel or titanium alloy.

[0010] Furthermore, the outer wall of the glove is provided with anti-slip texture.

[0011] Furthermore, the gloves are equipped with a locking mechanism.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0013] This invention designs an umbrella-like mechanism through a sliding sleeve and support rod, which can be directly installed on the endoscope sheath. During surgery, it can open the gap between the breast and the pectoralis major muscle, mechanically creating a cavity inside for more even support. The cavity also surrounds the endoscope sheath, resulting in better preservation of the surgical operating space and preventing complications such as flap necrosis and acidosis.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0023] like Figure 1-2 As shown in this embodiment, an auxiliary frame for creating a cavity in laparoscopic breast surgery includes a sliding sleeve 1, a fixing sleeve 2, a support rod 3, a diagonal rod 4, a handle glove 6, and a pull rod. The fixing sleeve 2, sliding sleeve 1, and handle glove 6 are sequentially fitted onto the outer wall of the endoscope sheath 7. The fixing sleeve 2 is detachably installed at the front end of the endoscope sheath 7 and remains fixed after installation. Both the sliding sleeve 1 and the handle glove 6 are slidably connected to the endoscope sheath 7.

[0024] One end of the support rod 3 is hinged to the sliding sleeve 1, and the other end extends outward towards the front end of the mirror sheath 7, as shown in the attached diagram. There are five support rods 3 and five diagonal rods 4. The support rods 3 are evenly distributed around the sliding sleeve 1 and connected to it. One end of the diagonal rod 4 is hinged to the fixed sleeve 2, and the other end is hinged to the non-endpoint of the support rod 3. Here, the diagonal rod 4 is connected to the support rod 3 from the axial half-point to the one-third point near the sliding sleeve 1. In this example, it is connected at the half-point. The lengths of the support rods 3 and diagonal rods 4 can be set according to the support requirements. The length ratio of the diagonal rod 4 to the support rod 3 is preferably controlled between 1:2 and 1:4. In this example, it is 1:2. The five support rods 3 correspond to the five diagonal rods 4, forming an umbrella-like structure. When the sliding sleeve 1 slides, it will cause the support rods 3 to open or close. When opened, it forms an umbrella-shaped support point to open the gap between the breast and the pectoralis major muscle, forming a cavity. Of course, it should be noted here that the front end of the support rod 3 is not sharp, and can be spherical or teardrop-shaped (not shown in the attached figure), that is, the top end is thicker than the rod body, which increases the support contact area when it is supported, and avoids damage to tissue.

[0025] The sliding of the sliding sleeve 1 is operated by the handle glove 6, which is connected to the sliding sleeve 1 via a connecting rod 5. The connecting rod 5 needs to have a certain rigidity so that the sliding sleeve 1 can move along with the handle glove 6. The outer wall of the handle glove 6 is provided with anti-slip texture to enhance friction and prevent slipping. After the sliding sleeve 1 moves into place, it needs to maintain its position. Therefore, a locking mechanism is provided on the outer wall of the handle glove 6. The locking mechanism can adopt existing technologies, such as nut locking (e.g., telescopic rod screw locking) or pressure block locking (e.g., automatic locking of a measuring tape). Locking is an existing technology and will not be described in detail here.

[0026] The materials for the support rod 3, diagonal rod 4, sliding sleeve 1, fixing sleeve 2, pull rod, and handle 6 must meet medical requirements. Stainless steel or titanium alloy can be used, similar to the material of the sheath 7.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
