Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to a novel single-hole laparoscope surgical incision protective cover. Background Art

[0002] Single-port laparoscopic surgery refers to a surgery performed by a surgeon who inserts a thin laparoscope and surgical instruments through only one suitable surgical incision and guides the operation of the surgical instruments through images transmitted to a monitor. This type of surgery is called laparoscopic surgery when performed in the abdominal cavity and thoracoscopic surgery when performed in the chest cavity.

[0003] After years of development, surgeons often place an incision protection cover in the incision during single-port laparoscopic surgery. The advantage is that it can protect the incision to the greatest extent, reduce damage to intercostal nerves and blood vessels, and reduce postoperative pain and bleeding. Another advantage is that the incision is propped open through a flexible channel, which is more conducive to the implementation of the operation. The existing incision protection cover includes a bottom ring, a top ring and a flexible channel. The bottom ring is inserted into the patient's body, the top ring is left outside the patient's body, and the flexible channel is between the inner and outer rings to prop the incision open. However, in actual surgical operations, this incision protection cover is still inconvenient to use, and is particularly unsuitable for the needs of single-port laparoscopic surgery, which is becoming increasingly popular. In clinical practice, both the laparoscope and surgical instruments need to pass through a single hole in the flexible channel. Due to the asynchronous movement of the laparoscope and the surgical instruments, the laparoscope and the surgical instruments often interfere with each other.

[0004] In single-port surgery, surgeons are accustomed to placing the laparoscope on one side or at the highest point of the single hole of the flexible channel, and frequently operate and switch surgical instruments on the other side or below. Compared with traditional three-port or multi-port laparoscopic surgery, single-port laparoscopic surgery greatly increases the difficulty of surgery and reduces the comfort experience of the surgeon and the hand holding the laparoscope. In addition, in some surgical operations, surgeons often need a closed and inflated operating environment, such as artificial pneumothorax for thymoma resection, artificial pneumoperitoneum for abdominal surgery, etc., which requires a single-port incision protective cover with closed accessories. Summary of the invention

[0005] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a novel single-hole laparoscope incision protective cover, which solves the technical problem that the existing incision protective cover is inconvenient to use.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A novel single-hole laparoscopic surgical incision protective cover comprises a bottom ring, a top ring and a flexible channel, wherein the lower end of the flexible channel is fixedly connected to the bottom ring, the top end of the flexible channel is wrapped around the top ring, and a laparoscope collar is installed inside the top ring; the laparoscope collar comprises an inflatable cavity,

[0008] The inflatable cavity comprises: a laparoscope ring area, which contracts in a non-inflated state to form a laparoscope ring cavity, wherein the laparoscope ring cavity connects the interior of a flexible channel with the exterior space of a laparoscope collar, and expands in an inflated state to expand the laparoscope ring cavity inwardly until the laparoscope ring cavity is sealed; a main operation ring area, which contracts in a non-inflated state to form a main operation ring cavity, wherein the main operation ring cavity connects the interior of a flexible channel with the exterior space of a laparoscope collar, and expands in an inflated state to expand the main operation ring cavity inwardly until the main operation ring cavity is sealed, and the main operation ring area is fixedly connected to the laparoscope ring area to form a whole; wherein the laparoscope ring area and the main operation ring area are both located inside the top ring.

[0009] Furthermore, the laparoscope collar also includes the auxiliary operation ring area, which contracts in a non-inflated state to form an auxiliary operation ring cavity, wherein the auxiliary operation ring cavity connects the interior of the flexible channel with the external space of the laparoscope collar, and the auxiliary operation ring area expands in an inflated state to expand the auxiliary operation ring cavity inward until the auxiliary operation ring cavity is sealed;

[0010] The auxiliary operation ring area is fixedly connected with the main operation ring area / cavitary mirror ring area to form a whole;

[0011] The auxiliary operation ring is provided as at least one group.

[0012] Furthermore, the auxiliary operation ring areas are set into two groups.

[0013] Furthermore, the two groups of auxiliary operation ring areas are respectively located outside the main operation ring area / cavity mirror ring area, and the auxiliary operation ring areas are distributed in a mirror image.

[0014] Furthermore, the laparoscope ring includes hooks, which are fixedly connected to the main operation ring area / laparoscopic ring area to form a whole, and the hooks are buckled on the top ring wrapped with the flexible channel, and at least one group of hooks is provided.

[0015] Furthermore, the hooks are arranged in two groups.

[0016] Furthermore, the hook is elastic, and when an external force pushes the hook to bend outward, the hook is separated from the top ring.

[0017] Furthermore, an elastic pressing block is fixedly installed on the inner side of the hook.

[0018] Furthermore, the maximum inner diameter of the laparoscope annulus cavity is 10-15 mm.

[0019] Furthermore, an air nozzle is provided on the laparoscope ring, and the laparoscope ring area, the main operation ring area and the internal cavities of the auxiliary operation ring area in the inflation cavity of the laparoscope ring are communicated with each other.

[0020] Beneficial effects of the present invention:

[0021] 1. The present invention isolates the laparoscope from the surgical instruments by providing the laparoscope annulus cavity and the main operation annulus cavity, which can reduce the mutual interference between the laparoscope and the surgical instruments during the operation, reduce the difficulty of the operation, and improve the comfort of the hand holding the laparoscope;

[0022] 2. The flexible channel of the present invention is wrapped around the top ring. During the surgical operation, the top ring is rolled according to the needs to release or wrap the flexible channel, thereby adapting to adjust the length of the flexible channel between the top ring and the bottom ring;

[0023] 3. The present invention isolates the auxiliary surgical instrument from the main surgical instrument by providing the auxiliary operation ring cavity and the main operation ring cavity, which can reduce the mutual interference between the auxiliary surgical instrument and the surgical instrument during the operation and reduce the difficulty of the operation;

[0024] 4. When a closed and inflated operating environment is required, the present invention inflates the laparoscope ring area, the main operation ring area and the auxiliary operation ring area in the inflatable cavity of the laparoscope ring through the air nozzle until the laparoscope ring area, the main operation ring area and the auxiliary operation ring area are inflated and closed, so that the flexible channel is relatively isolated from the outside world, forming a closed and inflated operating environment. At the same time, during the operation, the closed laparoscope ring cavity, the main operation ring cavity and the auxiliary operation ring cavity have a certain elastic recovery ability to open, which is suitable for the entry, exit and switching of slender instruments during surgery;

[0025] 5. The present invention clamps the laparoscope collar on the inner side of the top ring by means of a hook. This arrangement ensures that the laparoscope collar is always on the inner side of the top ring (i.e., the top of the entire incision protection cover), making it easy for the laparoscope, main surgical instruments, and auxiliary surgical instruments to pass through.

[0026] 6. The present invention uses the hook to roll the top ring to release or wrap the flexible channel, and does not interfere with the release or wrapping of the flexible channel, so that the flexible channel can be released or wrapped normally;

[0027] 7. The present invention is detachable between the laparoscope collar and the top sealing cover through the hook, and the laparoscope collar of the top ring can be installed or removed according to actual surgical needs, which is suitable for different surgical scenarios.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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.

[0033] like Figures 1 to 3 As shown, embodiment one:

[0034] A novel single-hole laparoscopic surgical incision protective cover comprises a bottom ring 1, a top ring 2 and a flexible channel 3, wherein the lower end of the flexible channel 3 is fixedly connected to the bottom ring 1, and the top end of the flexible channel 3 is wrapped around the top ring 2; a laparoscope sleeve ring 4 is installed inside the top ring 2;

[0035] The laparoscope collar 4 includes an inflatable cavity.

[0036] The inflatable cavity includes: a laparoscope ring area, which contracts in a non-inflated state to form a laparoscope ring cavity 41, wherein the laparoscope ring cavity 41 connects the interior of the flexible channel 3 with the external space of the laparoscope collar 4, and the laparoscope ring area expands in an inflated state to expand the laparoscope ring cavity 41 inward until the laparoscope ring cavity 41 is sealed;

[0037] A main operation ring region, wherein the main operation ring region contracts in a non-inflated state to form a main operation ring cavity 42, wherein the main operation ring cavity 42 connects the interior of the flexible channel 3 with the exterior space of the laparoscope collar 4, and the main operation ring region expands in an inflated state to expand the main operation ring cavity 42 inward until the main operation ring cavity 42 is sealed, and the main operation ring region is fixedly connected with the laparoscope ring region to form a whole;

[0038] The laparoscope ring area and the main operation ring area are both located inside the top ring 2.

[0039] The bottom ring 1 and the top ring 2 are both made of elastic plastic material, and can be arbitrarily deformed according to actual needs, so that the incision protection cover can be inserted into the surgical site; the flexible channel 3 is made of silicone film material, which is convenient for wrapping on the top ring 2.

[0040] The maximum inner diameter of the laparoscope annulus cavity 41 is preferably 10-15 mm. The inner diameter of the laparoscope annulus cavity 41 is designed accordingly according to the actual diameter of the laparoscope, so that the laparoscope annulus cavity 41 fits better with the placed laparoscope.

[0041] During the operation, the laparoscope is inserted into the patient's body through the laparoscope annulus cavity 41, and the surgical instruments are inserted through the main operation annulus cavity 42 to perform the operation. Compared with the prior art, the laparoscope and the surgical instruments are isolated by providing the laparoscope annulus cavity 41 and the main operation annulus cavity 42, which can reduce the mutual interference between the laparoscope and the surgical instruments during the operation, reduce the difficulty of the operation, and improve the comfort of the hand holding the laparoscope.

[0042] According to actual surgical needs (surgeons often need a closed and inflated operating environment, such as artificial pneumothorax for thymoma resection, artificial pneumoperitoneum for abdominal surgery, etc., which requires a single-hole incision protective cover with closed accessories), the laparoscope ring area and the main operation ring area are inflated until the laparoscope ring cavity 41 and the main operation ring cavity 42 expand inward and close, so that the inside of the flexible channel 3 is isolated from the external space of the laparoscope ring 4, so as to meet the surgical needs;

[0043] At the same time, the flexible channel 3 is wrapped around the top ring 2. During the surgical operation, the top ring 2 is rolled according to needs to release or wrap the flexible channel 3, thereby being able to adapt to and adjust the length of the flexible channel 3 between the top ring 2 and the bottom ring 1.

[0044] Embodiment 2

[0045] Based on the above embodiment, the laparoscope ring 4 further includes an auxiliary operation ring 43.

[0046] An auxiliary operation ring region, wherein the auxiliary operation ring region contracts in a non-inflated state to form an auxiliary operation ring cavity 43, wherein the auxiliary operation ring cavity 43 connects the interior of the flexible channel 3 with the exterior space of the laparoscope collar 4, and the auxiliary operation ring region expands in an inflated state to expand the auxiliary operation ring cavity 43 inwardly until the auxiliary operation ring cavity 43 is sealed;

[0047] The auxiliary operation ring area is fixedly connected with the main operation ring area / cavitary mirror ring area to form a whole;

[0048] The auxiliary operation ring 43 is provided as at least one set.

[0049] During the surgical operation, the surgical instruments are further divided into main surgical instruments and auxiliary surgical instruments. The main surgical instruments are passed through the main operation ring cavity 42, and the auxiliary surgical instruments are passed through the auxiliary operation ring cavity 43 to perform surgical operations. Compared with the prior art, the auxiliary surgical instruments are isolated from the main surgical instruments by setting the auxiliary operation ring cavity 43 and the main operation ring cavity 42, which can reduce the mutual interference between the auxiliary surgical instruments and the surgical instruments during the operation, reduce the difficulty of the operation, and improve the comfort experience of the mirror holding hand.

[0050] In actual use, it is preferred that the auxiliary operation ring areas are set into two groups. In order not to reduce the internal placement space of the main operation ring area / laparoscopic ring area, the two groups of auxiliary operation ring areas are respectively located outside the main operation ring area / laparoscopic ring area. At the same time, the auxiliary operation ring areas are distributed in a mirror-like manner, which is convenient for distinguishing and placing auxiliary surgical instruments.

[0051] Embodiment 3

[0052] Based on Example 1 / Example 2, the laparoscope ring 4 includes a hook 44, which is fixedly connected to the main operation ring area / laparoscopic ring area to form a whole, and the hook 44 is buckled on the top ring 2 wrapped with the flexible channel 3, and at least one group of hooks 44 is provided.

[0053] The hook 44 is elastic, and when an external force pushes the hook 44 to bend outward, the hook 44 is separated from the top ring 2.

[0054] When in use, the hook 44 is bent outward by external force, and the laparoscope ring 4 is clamped on the inner side of the top ring 2. Through such a setting, it can first ensure that the laparoscope ring 4 is always on the inner side of the top ring 2 (that is, the top of the incision protection cover as a whole), so that the laparoscope, the main surgical instrument and the auxiliary surgical instrument can pass through the corresponding laparoscope ring cavity 41, the main operation ring cavity 42 and the auxiliary operation ring cavity 43.

[0055] Secondly, when rolling the top ring 2 to release or wrap the flexible channel 3, it will not interfere with the release or wrapping of the flexible channel 3, so that the flexible channel 3 can be released or wrapped normally; further, the laparoscopic ring 4 and the top ring 2 are detachable, and the laparoscopic ring 4 of the top ring 2 can be installed or removed according to actual surgical needs (surgeons often need a closed and inflated operating environment, such as thymoma resection under artificial pneumothorax, abdominal surgery under artificial pneumoperitoneum, etc., which requires a single-hole incision protective cover with closed accessories).

[0056] In actual use, it is preferred that the hooks 44 are arranged in two groups, and the laparoscope ring 4 can be stably and smoothly installed in the top ring 2 through the buckling of the two hooks 44 .

[0057] Embodiment 4

[0058] On the basis of the second embodiment, an elastic pressing block is fixedly installed on the inner side of the hook 44. When the hook 44 is buckled on the top ring 2, the elastic pressing block squeezes the top ring 2 to keep the hook 44 in a stable state.

[0059] The elastic pressing block is made of elastic plastic material.

[0060] Embodiment 5

[0061] On the basis of implementation one to implementation four, a gas nozzle is provided on the laparoscope ring 4, and the laparoscope ring area, the main operation ring area and the auxiliary operation ring area in the inflation cavity of the laparoscope ring 4 are connected to each other;

[0062] In actual use, the laparoscope ring area, the main operation ring area and the auxiliary operation ring area in the inflatable cavity of the laparoscope ring 4 are exhausted through the air nozzle, so that the laparoscope ring cavity 41, the main operation ring cavity 42 and the auxiliary operation ring cavity 43 are respectively used for the corresponding laparoscope, main surgical instruments and auxiliary surgical instruments to pass through after exhaust;

[0063] When a closed and inflated operating environment is required, the laparoscope ring area, the main operation ring area and the auxiliary operation ring area in the inflation cavity of the laparoscope ring 4 are inflated through the air nozzle until the laparoscope ring area, the main operation ring area and the auxiliary operation ring area are inflated and closed, so that the flexible channel 3 is relatively isolated from the outside world, forming a closed and inflated operating environment. At the same time, during operation, the closed laparoscope ring cavity 41, the main operation ring cavity 42, and the auxiliary operation ring cavity 43 have a certain ability to elastically restore the opening. Specifically, when foreign objects such as slender instruments are inserted into the laparoscope ring cavity 41, the main operation ring cavity 42 or the auxiliary operation ring cavity 43, the laparoscope ring cavity 41, the main operation ring cavity 42 or the auxiliary operation ring cavity 43 adapt to the side wall of the slender instrument, thereby ensuring a relatively closed and inflated operating environment while allowing the entry, exit and switching of slender instruments during surgery.
