Description

Technical Field

[0001] The invention relates to the technical field of surgical instruments, and in particular to a dual-purpose surgical retractor. Background Art

[0002] Brain retractors (i.e., brain pressure plates) are often used in neurosurgery or orbital surgery to gently retract tissues. They have a good effect in pressing, pulling, 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, are very small, usually only 1mm thick. Brain retractors used clinically are mainly made of metal materials and can be bent into any shape.

[0004] However, because the brain retractor has an integrated sheet structure, it often presses on the diseased tissue or bleeding tissue by mistake during the operation, making it impossible to observe the diseased tissue, resulting in residual diseased tissue, or failing to completely stop the bleeding, thus affecting the operation. Summary of the invention

[0005] The invention provides a dual-purpose surgical retractor, which is used to solve the problems of residual diseased tissue or inability to completely stop bleeding caused by the lack of an observation window in the existing brain retractor.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A dual-purpose surgical retractor is a long metal sheet with rounded corners, the two ends of which are an observation area and a retraction area respectively. The observation area is provided with several through holes, and the through holes are circular or rounded rectangular in shape. A reinforcement structure is arranged on the outside or inside of the observation area, and the reinforcement structure is a reinforcement rib or a guide reinforcement plate, which is used to maintain the structure of the observation area.

[0007] Furthermore, the through hole is a circular observation hole, and a reinforcing rib is provided on the outer side of the observation hole perpendicularly and upwardly to the upper surface of the retractor.

[0008] Furthermore, the through hole is a rounded rectangular observation slot, and a drainage component is arranged on the outer side of the observation slot.

[0009] Furthermore, the drainage component includes a micro-drainage groove and a guide reinforcement plate.

[0010] Furthermore, the inner surface of the observation groove is inclined from bottom to top to form a guide surface, and the guide surface is connected with the micro drainage groove.

[0011] Furthermore, the micro-drainage groove is formed by an inward depression of the upper surface of the retractor, one end of which opens on the guide surface, and the other end opens on the side surface of the retractor.

[0012] Furthermore, the guide reinforcement plate is arranged on the left or right side of the observation slot and between two adjacent observation slots. The observation slot is a rectangular structure arranged upward perpendicular to the upper surface of the retractor, and the side surface facing the observation slot is concave inward to form a guide arc.

[0013] Furthermore, the observation area and the retraction area each occupy 1 / 3 of the length of the retractor.

[0014] Furthermore, the observation area is an inclined observation area, the thickness of which gradually decreases in the direction away from the retractor area, and the thickness at the minimum point is 1 / 2 of the thickness of the retractor.

[0015] Furthermore, the height of the reinforcement structure is 0.3-1 mm.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an observation area so that the retractor has an observation function, which is helpful for observing whether there is residual diseased tissue and finding the bleeding point when bleeding occurs. By arranging reinforcing mechanisms, reinforcing ribs or flow guide reinforcing plates on the outside and inside of the observation area, deformation or even breakage of the observation area during use due to the thinness and easy deformation of the tractor as a whole is avoided, and the manufacturing is also very easy; The drainage channel is constructed by the drainage surface, the drainage arc and the micro drainage groove, which is suitable for maintaining a clean field of vision to the greatest extent and quickly finding the bleeding point when there is a bleeding point during the operation; Taking into account the cost and difficulty of processing, constructing an inclined observation area is not only conducive to observation, but also plays a role in drainage to a certain extent, which is conducive to maintaining a clear visual environment.

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The retractor of the present invention is an optimized improvement based on the brain retractor. Because the space of the use position is limited, the size of the original retractor needs to be retained; in addition, the original retractor is easily deformed by force and can be adjusted to a suitable angle and shape, which is convenient to use and should also be retained. The main optimization of the present invention is that it is necessary to set an observation area on the retractor to observe whether there is residual diseased tissue or the location of bleeding points; in addition, in the case of bleeding, it is also necessary to ensure that there is enough observation field, so the problem of blood drainage in the observation area needs to be considered. Example 1

[0021] This embodiment provides a dual-purpose surgical retractor, such as Figure 1 As shown, the whole is in the shape of a long thin sheet, where the thin sheet refers to a metal sheet with a thickness of about 1 mm and rounded corners. An observation area 100 is set at one end of the dual-purpose retractor 10, and the other end is a common retraction area 200. In this embodiment, the observation area 100 is composed of a plurality of observation holes 110 that pass through the dual-purpose retractor 10 from top to bottom.

[0022] However, as the number of observation holes 110 increases, since the thickness of the dual-purpose retractor 10 is about 1 mm, the observation area 100 is easily deformed or broken during use. Figure 2 As shown, a reinforcing rib 130 needs to be provided on the outside of the observation area 100. The reinforcing rib 130 is provided vertically upwardly to the upper surface of the dual-purpose retractor 10 and has a height of 0.3-1 mm. The reinforcing rib 130 surrounds the observation area 100 and plays a role in strengthening support.

[0023] As a preferred method, the reinforcing ribs can be made of titanium alloy material added by laser cladding technology. Titanium alloy has high strength, low density and good biocompatibility. At this time, the strength of the observation area can be significantly improved without significantly increasing the overall weight and thickness of the retractor, avoiding stress concentration and fracture problems caused by drilling. Example 2

[0024] On the basis of Example 1, this embodiment optimizes the structure of the observation area 100, enlarges the observation window, and at the same time takes into account the problem of blood drainage. Figure 3 As shown, the observation area 100 in this embodiment is composed of a plurality of rectangular slots 121; Figure 5 As described above, the slot 121 is a through hole that penetrates the upper and lower surfaces of the dual-purpose retractor 10, but the inner surface of the slot 121 is inclined from bottom to top to form a guide surface 122, and any position of the upper edge of the slot 121 is connected to the micro-drainage groove 140. In this embodiment, the center of the upper edge of the slot 121 is connected upward and downward with a micro-drainage groove 121, and the micro-drainage groove 121 is formed by inward depression from the surface of the dual-purpose retractor 10, which plays a role in capillary drainage. A small amount of blood exudate can be drained through the guide surface 122 and the micro-drainage groove 140, thereby providing a clean observation field in the observation slot 120. Figure 4 As shown, in addition to the micro-drainage groove 140, the present embodiment also provides several flow guide reinforcement plates 150, which are located on one side of the observation groove 120 or between two adjacent observation grooves 120. The flow guide reinforcement plate 150 is a rectangular parallelepiped structure vertically upwardly arranged from the surface of the dual-purpose retractor 10, and the rectangular parallelepiped surface on the side close to the observation groove 120 is recessed inward to form a flow guide arc. The height of the flow guide reinforcement plate 150 is equivalent to the height of the reinforcing rib 130, which can play a reinforcing effect and prevent the observation groove 120 from being deformed or broken during use; in addition, the flow guide arc formed by the flow guide reinforcement plate 150, in conjunction with the flow guide surface 122, can guide bleeding with a large flow rate, at this time, the field of vision in the observation area 100 can be kept clean to the maximum extent, thereby quickly finding the bleeding point; in the process of finding the bleeding point, the position of the observation groove 120 can also be used for step-by-step investigation, at this time, the observation groove 120 is equivalent to being partitioned, forming a reference, which can improve the efficiency of investigation. Example 3

[0025] Based on Example 1 and Example 2, the solution of this embodiment is optimized by comprehensively considering the manufacturing cost. Specifically: Figure 6 As shown, the thickness of the observation area 100 decreases from the right (the side close to the retracting area 200) to the left to form an inclined 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 of the left third area decreases, and the minimum thickness is 1 / 2 of the thickness of the dual-purpose retractor 10.

[0026] The retractor in this embodiment constructs a slope, and when blood seeps out, it will flow out along the slope, playing a role in drainage; in addition, during normal observation, observation holes 110 at different positions have different observation fields of view. For example, the observation holes 110 at positions with smaller thickness have better observation fields of view because the height of the observation holes 110 is lower. During observation, if further observation is required, it can be achieved by moving the position of the observation area 100.

[0027] Of course, in order to strengthen the structure of the observation area and avoid deformation, it is also necessary to add reinforcing ribs 130 on the outside of the observation area.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
