Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a hole annular distribution incision protector. Background Art

[0002] An incision protector is a disposable device used in minimally invasive laparoscopic surgery to protect the patient's incision and support the establishment of pneumoperitoneum. Minimally invasive laparoscopic surgery includes small tissue resections such as cholecystectomy, and relatively few instruments are used in small tissue resections.

[0003] The existing incision protector has a cover hole position that cannot be changed, resulting in low smoothness of operation during surgery.

[0004] When removing tissue with existing incision protectors, the sheath is not large enough to support the removal of certain tissues (such as the gallbladder itself and gallstones). Therefore, the tissue needs to be temporarily placed inside the patient during surgery, and the incision protector can only be removed after the wound is sutured. During surgery, the placed stones may fall out due to visceral movement. If the stones are lost, they need to be searched for inside the patient, which not only makes tissue removal inconvenient, but also increases the risk of surgery.

[0005] Therefore, a hole annular distribution cutout protector is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that the empty space of the medical device cover cannot be changed and the incision protector needs to be removed before removing the tissue, and to propose an incision protector with an annular distribution of holes.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A hole-annularly distributed incision protector comprises a fixing ring, an annular groove is provided at the bottom of the fixing ring, an incision protection sleeve is sleeved in the annular groove, fixing ears are provided on both sides of the fixing ring, a clamping ring is provided at the top of the fixing ring, a rotating cover is clamped to the top of the fixing ring through the clamping ring, an inner lining is provided inside the rotating cover, and an instrument sheath is sleeved on the top of the lining.

[0009] Preferably, a silicone strip is bonded to the surface of the fixing ear, and a silicone sheet is bonded to the bottom surface of the fixing ear.

[0010] Preferably, the material of the clamping ring is medical plastic.

[0011] Preferably, a removal port is provided in the center of the rotating cover, a removal sheath is threadedly connected to the top of the removal port, a protective film is fixedly connected to the inside of the removal sheath, an operating port is provided around the removal port on the surface of the rotating cover, a groove for a matching clamping ring is provided on the bottom of the rotating cover, and ears are fixedly connected to both sides of the rotating cover.

[0012] Preferably, an air passage is provided on a surface of the rotary cover close to the edge, and an air pipe is connected to the air passage.

[0013] Preferably, the inner lining includes a fixed membrane, the top of the fixed membrane is fixedly connected to the bottom of the rotating cover, and a through hole matching the removal port and the trachea is opened on the surface of the fixed membrane.

[0014] Preferably, a membrane tube is provided on the surface of the fixed membrane corresponding to the operation port, and the top end of the membrane tube is sleeved with the instrument sheath.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model is provided with a rotating cover and an inner liner. During the operation, the fixing ear is pressed to make the fixing ring close to the patient's skin through the friction of the silicone sheet, so as to prevent the fixing ring from rotating with the rotating cover. The rotating cover is rotated along the fixing ring by pushing the ear. After rotating to a suitable position, the friction between the rotating cover, the clamping ring and the fixing ring is used to position the cover, so as to adjust the working angle. When it is necessary to remove tissue, the removal instrument is inserted into the removal sheath, passed through the removal sheath and then extended into the patient's body from the removal port. When the removed tissue passes through the removal sheath, the protective film inside the removal sheath is squeezed, and the protective film is expanded due to the elasticity of the protective film, thereby allowing the tissue to pass through. There is no need to remove the incision protector as a whole, thereby achieving the effect of facilitating tissue removal.

[0017] 2. The utility model sets an inner lining and connects the instrument sheath through a membrane tube. When adjusting, the inner lining rotates with the rotating cover, driving the instrument sheath to change the working position. During surgery, the membrane tube can bend due to its own toughness, so that the doctor has a more comfortable working angle during surgery. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1-6 A hole-annular distribution incision protector comprises a fixing ring 1, an annular groove 2 is provided at the bottom of the fixing ring 1, an incision protection sleeve 3 is sleeved in the annular groove 2, fixing ears 4 are provided on both sides of the fixing ring 1, a clamping ring 5 is provided on the top of the fixing ring 1, a rotating cover 6 is clamped on the top of the fixing ring 1 through the clamping ring 5, an inner lining is provided inside the rotating cover 6, and an instrument sheath 7 is sleeved on the top of the lining.

[0027] Furthermore, a silicone strip 8 is bonded to the surface of the fixing ear 4 , and a silicone sheet 9 is bonded to the bottom surface of the fixing ear 4 .

[0028] A further advantage of adopting the above method is that, during adjustment, pressing the fixing ear 4 allows the fixing ring 1 to adhere to the patient's skin through the friction of the silicone sheet 9, preventing the fixing ring 1 from rotating with the rotating cover 6, and pushing the ear piece 14 to cause the rotating cover 6 to rotate along the fixing ring 1.

[0029] Furthermore, the material of the clamping ring 5 is set to be medical plastic, so that the clamping ring 5 can be deformed by extrusion during assembly to enter the clamping groove 13.

[0030] Furthermore, a removal port 10 is provided at the center of the rotating cover 6, a removal sheath 11 is threadedly connected to the top of the removal port 10, a protective film 1101 is fixedly connected inside the removal sheath 11, an operation port 12 is provided on the surface of the rotating cover 6 around the removal port 10, a card groove 13 for matching the clamping ring 5 is provided on the bottom of the rotating cover 6, ear pieces 14 are fixedly connected on both sides of the rotating cover 6, an air passage 15 is provided on the surface of the rotating cover 6 near the edge, and an air pipe 16 is inserted into the air passage 15.

[0031] A further advantage of adopting the above method is that when tissue needs to be removed, the removal instrument is inserted into the removal sheath 11, passed through the removal sheath 11, and then extended into the patient's body from the removal port 10 to remove the removed tissue. After removal, the removal sheath 11 is reset without the need to remove the entire sheath, thereby achieving the effect of facilitating tissue removal.

[0032] Furthermore, the inner lining includes a fixed membrane 17, the top of the fixed membrane 17 is fixedly connected to the bottom of the rotating cover 6, the surface of the fixed membrane 17 is provided with a through hole matching the removal port 10 and the trachea 16, and a membrane tube 18 is provided on the surface of the fixed membrane 17 corresponding to the operation port 12, and the top of the membrane tube 18 is connected to the instrument sheath 7.

[0033] It should be noted that the instrument sheath 7 is an existing technology. According to the type of instrument, a suitable instrument sheath 7 can be freely selected to be connected with the membrane tube 18. The top diameter of the membrane tube 18 is smaller than the bottom diameter, so that the membrane tube 18 can fix the instrument sheath 7 by shrinking the top and seal the edge of the instrument sheath 7 at the same time.

[0034] A further advantage of adopting the above method is that the instrument sheath 7 is connected by the membrane tube 18. During adjustment, the inner lining rotates with the rotating cover 6, driving the instrument sheath 7 to change its working position. During surgery, the membrane tube 18 can be bent through toughness, so that the doctor has a more comfortable working angle during surgery.

[0035] When the utility model is used, the incision protection cover 3 is placed into the incision, the top end of the incision protection cover 3 is sleeved with the annular groove 2, the fixing ring 1 is fixed at the incision, pneumoperitoneum is established through the trachea 16, and the surgical instrument is inserted from the instrument sheath 7 to perform the operation;

[0036] When the position of the cover hole needs to be adjusted during surgery, the fixing ear 4 is pressed to make the fixing ring 1 close to the patient's skin through the friction of the silicone sheet 9, so as to prevent the fixing ring 1 from rotating with the rotating cover 6. The rotating cover 6 is rotated along the fixing ring 1 by pushing the ear piece 14. After rotating to a suitable position, the friction between the rotating cover 6, the clamping ring 5 and the fixing ring 1 is used to position the cover hole, thereby achieving the function of adjusting the cover hole position during surgery. During surgery, the membrane tube 18 can be bent by toughness, so that the doctor can have a more comfortable working angle when performing surgery.

[0037] When it is necessary to remove tissue, the removal instrument is inserted into the removal sheath 11, passed through the removal sheath 11 and then extended into the patient's body from the removal port 10. When the removed tissue passes through the removal sheath 11, it squeezes the protective film 1101 inside the removal sheath 11. The elasticity of the protective film 1101 causes the protective film 1101 to expand, allowing the tissue to pass through. There is no need to remove the incision protector as a whole, thereby facilitating the removal of tissue.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
