Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and particularly relates to a left - hand wearable tissue retractor for surgical operations. Background Art

[0002] In surgical operations, the exposure of the surgical field is very important. A good surgical field enables the surgeon to clearly distinguish tissue structures, make correct surgical decisions, and accurately perform surgical operations, avoiding accidental injury to important blood vessels, tissues, and organs, reducing risks such as surgical bleeding, shortening the operation time, and being beneficial to the postoperative recovery of patients.

[0003] The structures within the human body are extremely complex. In order to reduce surgical trauma, surgeons will choose relatively small surgical incisions, making the exposure of the surgical field even more difficult. The operating space deep within the patient's tissues and organs may be very narrow. During the operation, it is necessary to effectively push aside the surrounding tissues to expose the structure that the surgeon wants to operate on. At this time, the assistant will use surgical instruments to help the surgeon expose the field of view. However, too many surgical instruments will further interfere with the surgical field, making it difficult to create a good surgical field. If the surgeon can wear a suitable surgical auxiliary tool to push aside the surrounding tissues at this time, the exposure of the surgical field can be perfectly achieved. Summary of the Invention

[0004] The purpose of the present invention is to provide a left - hand wearable tissue retractor for surgical operations, which can fully push aside deep tissues, expose the target structure, and clearly distinguish tissue structures.

[0005] The present invention provides a left - hand wearable tissue retractor for surgical operations, including a U - shaped body composed of a lower pressing surface and an outer supporting surface. The U - shaped body is made of a flexible material. An elastic retractor plate is arranged through the U - shaped body from beginning to end. A pressure rod is arranged inside the U - shaped body near the lower pressing surface. The middle of the pressure rod is hinged to the retractor plate through a pressure rod fixed shaft. An elastic member is arranged at the end inside the U - shaped body near the lower pressing surface. The top and bottom of the elastic member are respectively fixedly connected to the pressure rod and the retractor plate. One end of the pressure rod away from the elastic member is connected to a transmission line. The transmission line bypasses a transmission group and is fixedly connected to one end of the retractor plate away from the elastic member. A non - slip layer is arranged at a position inside the U - shaped body opposite to the lower pressing surface.

[0006] Preferably, the elastic member is a compression spring.

[0007] Preferably, the non - slip layer is a wavy structure for increasing friction.

[0008] Preferably, finger sleeves for the four fingers of the left hand except the thumb to extend into are arranged on the non - slip layer.

[0009] Preferably, the finger sleeve is made of an elastic rubber strip.

[0010] Preferably, the length of the finger sleeve is equal to the length of the anti-slip layer.

[0011] Preferably, the transmission group includes an idler gear shaft for changing the output direction at the corner of the U-shaped body and a transmission shaft located on the side close to the outer supporting surface.

[0012] Preferably, the pressing surface is a smooth surface.

[0013] Preferably, the detachable anti-slip layer is made of a sticky silicone material and adheres to the pressing surface.

[0014] Advantageous effects:

[0015] The present invention provides a left-handed wearable tissue retractor for surgical operations. After the operator wears it on the left hand, the operator can control the opening and closing of the elastic member with the left hand, and then through the transmission of the transmission line, the outer supporting surface and the pressing surface are opened, so as to fully push open the deep tissues, expose the target structure, clearly distinguish the tissue structure, make correct surgical decisions, and accurately perform surgical operations, avoiding accidental injury to important blood vessels, tissues and organs, reducing risks such as surgical bleeding, shortening the surgical time, and being beneficial to the postoperative recovery of the patient.

[0024] Embodiment 1

[0025] A left - hand wearable tissue retractor for surgical operations, as Figures 1-3As shown, it includes a U-shaped body consisting of a lower pressure surface 1 and an outer support surface 2. The U-shaped body is made of flexible material, preferably medical flexible rubber. An elastic expansion plate 3 is penetrated from the beginning to the end of the U-shaped body. A pressure rod 4 is provided inside the U-shaped body near the lower pressure surface 1. The middle part of the pressure rod 4 is hinged to the expansion plate 3 through a pressure rod fixing shaft 5. A pressing spring 6 is provided at the end of the U-shaped body near the lower pressure surface 1. The top and bottom of the pressing spring 6 are respectively fixedly connected to the pressure rod 4 and the expansion plate 3. A transmission line 7 is connected to the end of the pressure rod 4 away from the pressing spring 6. The transmission line 7 bypasses the transmission group and is fixedly connected to the end of the expansion plate 3 away from the pressing spring 6. The transmission line 7 always maintains a certain angle with the expansion plate 3, so that the transmission line 7 can pull the expansion plate 3 downward; the transmission group includes an idle gear shaft 10 for changing the output direction located at the corner of the U-shaped body and a transmission shaft 11 located near the outer support surface 2. An anti-skid layer 8 is provided on the inner side of the U-shaped body at a position opposite to the lower pressing surface 1. The anti-skid layer 8 is a wavy structure for increasing friction. A finger cot 9 is provided on the anti-skid layer 8 for the four fingers of the left hand except the thumb to be inserted. The finger cot 9 is made of an elastic rubber strip. The length of the finger cot 9 is equal to the length of the anti-skid layer 8. A detachable anti-skid layer 12 is provided on the lower pressing surface 1. The detachable anti-skid layer 12 is a viscous silicone material and adheres to the lower pressing surface 1. The detachable anti-skid layer 12 can be torn off as needed to remove the anti-skid effect of the design.

[0026] (1) How to use the “closed” state:

[0027] Take out the left-hand wearable tissue spreader for surgical operation in the "closed" state, and the operator inserts the four fingers of the left hand except the thumb into the finger sleeve 9, and the four fingertips contact the anti-slip layer 8. The operator's left index finger is slightly relaxed, the pressing spring 6 is in a relaxed state, and the angle between the pressure rod 4 and the spreader plate 3 is large, so that the transmission line 7 has a large tension. This tension pulls the distal end of the spreader plate 3 after passing through the idle gear shaft 10, so that the spreader plate is in the "closed" state. The other four fingers slightly force the downward pressure surface 1 to contact and press down the tissue under the left hand. The downward pressure surface 1 and the detachable anti-slip layer 12 expand the effective area of the left hand contacting the tissue, so the operator can more effectively pry, pull, and push the tissue under the left hand. The detachable anti-slip layer 12 can effectively increase the friction between the glove and the tissue and reduce the sliding between the tissue and the operator's palm.

[0028] (2) How to use in the “open” state:

[0029] The surgeon wants to treat deep tissue structures, but the target structures are squeezed and blocked by the tissues above and below them, so the surgeon needs to use his left hand to expose the surgical field of view. The surgeon's left index finger slightly squeezes the pressing spring 6, and with the assistance of the pressure rod fixed shaft 5, the angle between the pressure rod 4 and the expansion plate 3 is reduced, the tension of the transmission line 7 is reduced, and after passing through the idle gear shaft 10 and the transmission shaft 11, the tension of the transmission line 7 on the far end of the expansion plate 3 is also reduced, so that the expansion plate 3 "opens its mouth" and presents an "expanded" state. At this time, the size of the "expansion" can be controlled by the pressure under the left index finger.

[0030] After deep tissue treatment is completed, the surgeon can continue to wear the surgical left-hand wearable tissue spreader in the "closed" state, or remove it and continue the operation.

[0031] The present invention has two states, "closed" and "open", corresponding to two functions; in the "closed" state, after wearing the device, the operator can effectively expand the effective contact area between the left hand and tissues and organs, so that it is more convenient to realize the actions of pulling, prying and pushing the tissues; in the "open" state, the operator can simultaneously push up the upper tissue and press down the lower tissue while expanding the contact area between the palm and the tissue, and conveniently adjust the size of the opening angle by the force of the index finger; the conversion between the "closed" and "open" states can be achieved only by pressing down and relaxing the index finger; the detachable anti-slip layer can meet the requirements of different situations.

[0032] It can be used in all laparotomy surgeries, and is more useful in cases where deep tissues need to be treated and deep surgical fields need to be exposed, such as orthopedics, hepatobiliary surgery, gastrointestinal surgery, urology, cardiothoracic surgery, etc.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
