Description

Technical Field

[0001] This utility model relates to the field of surgical instrument technology, specifically to a dual-purpose surgical retractor. Background Technology

[0002] Brain retractors (i.e., brain depressors) are commonly used in neurosurgery or orbitotomy to gently retract tissues. They play a good role in pressing, traction, and protecting tissues.

[0003] Because of the special location and limited operating space, the size of commonly used brain retractors, especially the width and thickness, is very small. The thickness is usually only 1mm. The brain retractors used in clinical practice are mainly made of metal materials and their shape can be bent at will.

[0004] However, because the brain retractor is a one-piece sheet structure, it is easy to accidentally press on diseased tissue or bleeding tissue during the operation, which may result in the inability to observe the diseased tissue, leaving residual diseased tissue, or failure to completely stop bleeding, thus affecting the operation. Utility Model Content

[0005] This invention provides a dual-purpose surgical retractor to solve problems such as residual lesions or inability to completely stop bleeding caused by the lack of an observation window in existing brain retractors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dual-purpose surgical retractor is a long, rounded, integrally formed metal sheet. The two ends of the dual-purpose retractor are an observation area and a retraction area, respectively. The observation area has several through holes, which are circular or rounded rectangular in shape. A reinforcing structure, which is a reinforcing rib or a flow-guiding reinforcement plate, is provided on the outer or inner side of the observation area to maintain the structure of the observation area.

[0008] Furthermore, the through hole is a circular observation hole, and a reinforcing rib is provided on the outer side of the observation hole perpendicular to the upper surface of the retractor.

[0009] Furthermore, the through hole is a rounded rectangular observation groove, and a drainage component is provided on the outside of the observation groove.

[0010] Furthermore, the drainage component includes a micro-drainage channel and a drainage enhancement plate.

[0011] Furthermore, the inner surface of the observation groove slopes upward to form a guide surface, and the guide surface is in communication with the micro-drainage groove.

[0012] Furthermore, the micro-drainage groove is formed by an inward indentation on the upper surface of the retractor, with one end opening on the guide surface and the other end opening on the side of the retractor.

[0013] Furthermore, the flow-guiding reinforcement plate is positioned on the left or right side of the observation slot and between two adjacent observation slots. The observation slot is a cuboid structure that is perpendicular to the upper surface of the puller and is upwardly oriented, with the side surface facing the observation slot recessed inward to form a flow-guiding arc.

[0014] Furthermore, the observation area and the retraction area each occupy 1 / 3 of the length of the retractor.

[0015] Furthermore, the observation area is an inclined observation area, the thickness of which gradually decreases in the direction away from the retraction area, and the minimum thickness is 1 / 2 of the thickness of the retractor.

[0016] Furthermore, the height of the reinforcing structure is 0.3-1mm.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention enables the retractor to have an observation function by setting an observation area, which is beneficial for observing whether there is residual diseased tissue and locating bleeding points when bleeding occurs.

[0019] By setting reinforcement mechanisms, reinforcing ribs or flow-guiding reinforcement plates on the outer and inner sides of the observation area, the deformation or even breakage during use is avoided because the observation area is easily deformed due to the thinness of the overall traction device. Moreover, it is very easy to manufacture.

[0020] By constructing a drainage channel through a drainage surface, drainage arc, and micro-drainage groove, it is suitable for maintaining a clean field of vision to the greatest extent while quickly locating bleeding points even when bleeding points are present during surgery.

[0021] Considering the cost and difficulty of processing, constructing an inclined observation area not only facilitates observation but also serves to guide the flow of people, thus helping to maintain a clear field of vision. Attached Figure Description

[0029] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This utility model relates to an optimized and improved brain retractor. Due to space constraints, the original retractor's dimensions need to be retained. Additionally, the original retractor, which is easily deformed under stress and can be adjusted to a suitable angle and shape for ease of use, should also be retained. The main optimization of this utility model lies in: the need to include an observation area on the retractor to observe for residual diseased tissue or the location of bleeding points; furthermore, sufficient field of view must be ensured in the event of bleeding, thus requiring consideration of blood drainage in the observation area. Example 1

[0031] This embodiment provides a dual-purpose surgical retractor, such as... Figure 1 As shown, it is generally a long, thin sheet, where "thin sheet" refers to a metal sheet with a thickness of about 1 mm, and the four corners are rounded. One end of the dual-purpose retractor 10 is provided with an observation area 100, and the other end is a regular retractor area 200. In this embodiment, the observation area 100 is composed of several observation holes 110 that run vertically through the dual-purpose retractor 10.

[0032] However, as the number of observation holes 110 increases, the observation area 100 is prone to deformation or breakage during use because the dual-purpose retractor 10 is approximately 1mm thick. Therefore, if... Figure 2As shown, a reinforcing rib 130 needs to be set on the outside of the observation area 100. The reinforcing rib 130 is set vertically to the upper surface of the dual-purpose retractor 10 and has a height of 0.3-1mm. It surrounds the observation area 100 and plays a role in strengthening the support.

[0033] As a preferred approach, the reinforcing ribs can be made of titanium alloy material added using laser cladding technology. Titanium alloy has high strength, low density, and good biocompatibility. In this case, the strength of the observation area can be significantly improved without significantly increasing the overall weight and thickness of the retractor, thus avoiding stress concentration and fracture problems caused by drilling. Example 2

[0034] Based on Example 1, this example optimizes the structure of the observation area 100, increases the observation window, and also takes into account the issue of blood drainage. Specifically: as follows Figure 3 As shown, the observation area 100 in this embodiment is composed of several rectangular slots 121; Figure 5 The slot 121 is a through hole penetrating the upper and lower surfaces of the dual-purpose retractor 10. However, the inner surface of the slot 121 slopes upward to form a guide surface 122. The upper edge of the slot 121 is connected to a micro-drainage groove 140 at any point. In this embodiment, a micro-drainage groove 121 is connected upward and downward at the center of the upper edge of the slot 121. The micro-drainage groove 121 is formed by an inward indentation from the surface of the dual-purpose retractor 10, serving as a capillary drainage mechanism. Small amounts of blood exudate can be drained through the guide surface 122 and the micro-drainage groove 140, thereby providing a clean observation field within the observation groove 120. Figure 4 As shown, in addition to the micro-drainage channel 140, this embodiment also includes several flow-guiding reinforcement plates 150. The flow-guiding reinforcement plates 150 are located on one side of the observation channel 120 or between two adjacent observation channels 120. The flow-guiding reinforcement plates 150 are cuboid structures vertically upwards from the surface of the dual-purpose retractor 10, with the cuboid surface near the observation channel 120 concave inwards to form a flow-guiding arc. The height of the flow-guiding reinforcement plates 150 is comparable to the height of the reinforcing ribs 130, which strengthens the structure and prevents deformation or breakage of the observation channel 120 during use. Furthermore, the flow-guiding arc formed by the flow-guiding reinforcement plates 150, in conjunction with the flow-guiding surface 122, can guide large volumes of bleeding, thus maximizing the cleanliness of the observation area 100 and enabling rapid detection of bleeding points. During the search for bleeding points, the positions of the observation channels 120 can be used for step-by-step investigation. In this case, the observation channels 120 are essentially partitioned, forming a reference point and improving the efficiency of the investigation. Example 3

[0035] Based on Examples 1 and 2, and taking into account manufacturing costs, the solution in this example is optimized. Specifically: as follows... Figure 6 As shown, the thickness of the observation area 100 decreases from right to left (the side closer to the retraction area 200) to form a sloping observation area 160. Specifically, the length of the observation area 100 is 1 / 3 of the length of the dual-purpose retractor 10, that is, the thickness decreases in the left third of the area, and the minimum thickness is 1 / 2 of the thickness of the dual-purpose retractor 10.

[0036] In this embodiment, the retractor creates a slope, which allows blood to flow out along the slope when it seeps out, thus serving as a drainage function. In addition, during normal observation, the observation holes 110 at different positions have different fields of view. For example, the observation holes 110 at the thinner position have a better field of view because the height of the observation holes 110 is lower. If further observation is needed during observation, it can be achieved by moving the position of the observation area 100.

[0037] Of course, in order to strengthen the structure of the observation area and prevent deformation, it is also necessary to add reinforcing ribs 130 on the outside of the observation area.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
