Description

Technical Field

[0001] The invention relates to a disposable multi-channel single-hole laparoscopic surgical puncture device, which belongs to a medical device and is suitable for puncturing human abdominal wall tissue during laparoscopic examination and surgery to establish a working channel for abdominal surgery. Background Art

[0002] Most multi-channel single-hole punctures are used in transumbilical single-hole laparoscopic surgery. During the operation, surgical instruments and equipment enter the abdominal cavity through the umbilical hole. After the surgical incision becomes one, the flexibility of the puncture is most important. Traditional punctures are made of plastic injection molding and are rigid tubes. Therefore, large swing angle surgery cannot be achieved. Therefore, only a few holes can be made in the abdomen, which causes more surgical trauma and has great surgical limitations. The same type of multi-channel single-hole punctures are fixed to the umbilical hole position in the abdomen by upper and lower clamps. Because the upper and lower clamps are too hard and fit too tightly to the abdomen, a large swing angle cannot be achieved, making it impossible for the instrument to reach the surgical site normally. The use of this puncture has great surgical limitations.

[0003] The operation of single-port laparoscopic surgery is limited by the number of channels, the surgical site is limited, and it is also difficult to pull the adjacent organs. At the same time, because the instrument placement site is relatively concentrated, it is difficult to form an operation triangle, and the instruments interfere with each other, affecting the operation and surgical field of view. Since the surgical incisions are all at the umbilicus, when performing surgery on the upper abdomen far from the umbilicus, it is necessary to create a larger swing angle for the puncture device, and the surgical instruments also need a larger angle. Therefore, it is very important for the puncture device to have a large swing angle without mutual interference, otherwise the surgical instruments cannot be flexibly operated. If the mutual pulling force is too large during operation, and the sealing cap is not designed with a large swing angle, the puncture device will leak, causing the operation to be unable to proceed normally. Summary of the invention

[0004] The purpose of the present invention is to provide a disposable multi-channel single-hole laparoscopic surgical puncture device to address the above-mentioned deficiencies. The puncture device is suitable for puncturing human abdominal wall tissue during laparoscopic examination and surgery to establish a working channel for abdominal surgery.

[0005] The disposable multi-channel single-hole laparoscopic surgical puncture device is realized by adopting the following technical solutions:

[0006] The disposable multi-channel single-hole laparoscopic surgical trocar consists of a multi-channel trocar assembly and an incision protection cover with an elastic pad. The lower part of the multi-channel trocar assembly is provided with an incision protection cover with an elastic pad.

[0007] The multi-channel trocar assembly comprises a sleeve 1, a sleeve 2, an air injection valve assembly and a trocar.

[0008] The puncture device comprises a puncture device body, a sealing cover is arranged on the upper part of the puncture device body, a sleeve tube 1 and a sleeve tube 2 are arranged on the sealing cover, an air injection valve assembly is arranged on the sealing cover, and the air injection valve assembly is connected to an air source.

[0009] A support ring is provided at the lower part of the puncture body with an anti-falling design, which is installed in conjunction with the outer ring of the incision protection cover to ensure the sealing of the surgical instruments in and out, and to increase the swing angle of the surgical instruments to expand the surgical range.

[0010] The connection between the sleeve 1, sleeve 2 and the cover is respectively designed as an elastic corrugated ring, so that the surgical instruments do not interfere with each other when in use. At least two sleeves 1 and 2 are provided.

[0011] The sleeve 1 and the sleeve 2 are provided with a sleeve base on the upper part, and are provided with a guide cover, a sealing cap and a gas blocking valve in order from top to bottom. The height of the sleeve 1 is higher than that of the sleeve 2, and is suitable for different surgical instruments to enter and exit.

[0012] The guide cover comprises a guide cover body, and a guide channel is arranged in the middle of the guide cover body.

[0013] The sealing cap comprises a sealing cap body, a sealing step and a connecting ring are arranged on the upper part of the sealing cap body, and the sealing step is connected to the sealing cap body through the connecting ring. The connecting ring is an ultra-thin connecting ring, which can increase the range of motion of the surgical instrument. A supporting sheet fixing step is arranged on the inner side of the upper part of the sealing cap body, which is used to install and fix the supporting sheet.

[0014] The lower part of the sealing cap body is set in a conical shape, and the bottom of the sealing cap body is provided with an instrument channel. During surgery, surgical instruments pass through the instrument channel and can achieve sealing.

[0015] The sealing cap is formed by integral injection molding of silica gel, silicone rubber, or rubber.

[0016] The support sheet has a support sheet body, and a mounting slot is provided on the upper part of the support sheet body, which cooperates with a support sheet fixing step provided on the inner side of the upper part of the sealing cap body, and is used to install and fix the support sheet in the sealing cap. A protective sheet is provided at the lower part of the support sheet body, and a support sheet instrument channel is provided at the bottom of the protective sheet.

[0017] The air blocking valve comprises an air blocking valve body, an air blocking valve outer ring is arranged at the upper end of the air blocking valve body, an elastic air blocking sealing sheet is arranged at the lower part of the air blocking valve body, and a cross cut is arranged on the elastic air blocking sealing sheet for serving as an instrument channel, which is a one-way sealing channel.

[0018] The sleeve 1, sleeve 2 and puncture device can be made of elastic soft material by one-time injection molding, and the elastic soft material is made of silica gel, silicone rubber, or rubber.

[0019] The gas injection valve assembly is composed of a gas injection joint, a gas injection sleeve, a gas injection switch, and a gas injection valve. The lower end of the gas injection joint is installed on the cover of the puncture device body. The upper end of the gas injection joint is connected to the gas outlet of the gas injection valve through the gas injection sleeve. The gas injection valve is equipped with a gas injection switch, and the gas inlet pipe of the gas injection valve is connected to the gas source.

[0020] The gas injection valve assembly is provided with at least one group.

[0021] The incision protection sleeve with elastic pad includes an outer ring, an inner ring, a high elastic gasket, a pull ring and a pull rope. The outer ring is connected to the inner ring, the outer ring is connected to the inner ring, the inner cavities of the outer ring and the inner ring are provided with surgical instrument channels, and the high elastic gasket is installed at the connection between the outer ring and the inner ring. The high elastic gasket increases the swing angle of the surgical instrument and expands the surgical range.

[0022] The pull ring is connected to the lower end of the inner ring through a pull rope. After the operation, the pull ring is pulled and the device can be easily pulled out from the abdominal incision through the pull rope.

[0023] The inner ring of the outer ring is provided with a support ring assembly groove for installing the porous puncture device support ring.

[0024] An elastic support ring is arranged at the lower end of the inner ring to support the inner ring, increase the swing angle of the inner ring surgical instrument, and expand the surgical range.

[0025] The inner ring is trumpet-shaped, with a small upper part and a large lower part, so that the incision protection cover will not slip out of the abdominal incision during surgery.

[0026] When the disposable multi-channel single-hole laparoscopic surgical puncture device is used, the multi-channel puncture device assembly is used in conjunction with the incision protection cover with an elastic pad. When used in surgery, the incision protection cover with an elastic pad is first installed in the abdominal incision, and the puncture device of the multi-channel puncture device assembly is installed in the support ring assembly groove set in the inner ring of the outer ring through the support ring, and is connected to the incision protection cover with an elastic pad. During surgery, opening the gas injection valve to inject gas into the abdominal cavity can form pneumoperitoneum, maintain pneumoperitoneum pressure, and establish a working channel for surgical instruments or endoscopes. A variety of surgical instruments and endoscopes can enter the abdominal cavity from different puncture holes of the multi-hole puncture device, and abdominal surgery can be performed under the monitoring of endoscopes and X-ray machines. Since the high-elastic gasket is installed at the connection between the outer ring and the inner ring, the high-elastic gasket increases the swing angle of the surgical instrument, making the surgical range larger. Since the lower end of the inner ring is provided with an elastic support ring for supporting the inner ring, the swing angle of the surgical instrument in the inner ring is increased, making the surgical range larger.

[0027] The pull ring is connected to the lower end of the inner ring through a pull rope. When the operation is finished, there is no need to detach the main body. The pull ring can be directly lifted to pull out the incision protection cover with the elastic pad, saving operation time.

[0028] The disposable multi-channel single-hole laparoscopic surgical puncture is reasonably designed, compact in structure, and easy to use. After the multi-channel puncture assembly is matched with the incision protection cover, it forms a closed space with the abdominal cavity. The gas injection valve assembly is provided with at least one group. When gas is injected, pneumoperitoneum can be formed, pneumoperitoneum pressure can be maintained, and a working channel can be established for surgical instruments or endoscopes. Since the multi-channel puncture assembly is provided with multiple puncture channels, a variety of surgical instruments and endoscopes can enter the abdominal cavity from different puncture holes of the multi-hole puncture, and abdominal surgery can be performed under the monitoring of endoscopes and X-ray machines, which is convenient to use. Since the connection between the sleeve one, the sleeve two and the cover is respectively provided with an elastic corrugated design, the surgical instruments do not interfere with each other during use. Since the lower part of the puncture body is provided with a support ring, an anti-falling design, and the outer ring of the incision protection cover is installed in coordination with each other, the sealing of the surgical instruments in and out is ensured, and the swing angle of the surgical instruments is increased, so that the surgical range is larger. Since the pull ring is connected to the lower end of the inner ring by a pull rope, when the operation is finished, there is no need to detach the main body, and the pull ring can be directly lifted to pull out the incision protection cover with the elastic pad, thus saving operation time.

[0029] Since a high elastic gasket is provided and installed at the connection between the outer ring and the inner ring, the high elastic gasket increases the swing angle of the surgical instrument, so that the surgical range is larger. Since an elastic support ring is provided at the lower end of the inner ring to support the inner ring, the swing angle of the surgical instrument of the inner ring is increased, so that the surgical range is larger.

[0030] The incision protection sleeve with elastic pad plays the role of elastically supporting the multi-channel puncture assembly during laparoscopic examination and surgery, so that the assembly can have a greater degree of freedom of swing angle in the abdominal position, thereby expanding the scope of surgery.

[0031] When it is necessary to perform an operation far away from the umbilicus, the elastic pad can allow the main body of the puncture device to have a larger swing angle, thereby facilitating the surgical instrument to have a large swing angle, allowing the surgical instrument to easily reach the surgical site for surgery.
