Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a thoracic and abdominal cavity catheter placement device. Background Art

[0002] Thoracic and abdominal catheterization is a common surgical procedure, which is used to insert a catheter into the patient's chest or abdomen for drug treatment, drainage, nutritional support, etc. At present, common thoracic and abdominal catheterization devices usually use conventional medical forceps to pierce the patient's chest and abdomen at an inclined angle, and then stretch the patient's skin tissue to insert the catheter. Due to the lack of special medical forceps, it is difficult to pierce the patient's skin. The opening of the patient's skin is irregular in shape and small in size. Inserting the catheter can easily cause harm to the patient, and the catheter can easily be pulled out during the withdrawal of the conventional medical forceps, which brings many inconveniences to the treatment process. Therefore, a thoracic and abdominal catheterization device is urgently needed. Summary of the invention

[0038] The embodiment of the present invention provides a thoracic and abdominal cavity tube placement device, comprising a first hand-held part 120, a second hand-held part 110, a first semi-cylinder 210, a second semi-cylinder 220 and a puncture member 300, wherein the second hand-held part 110 is hinged to the middle part of the first hand-held part 120; the first end of the first semi-cylinder 210 is connected to the first end of the first hand-held part 120; the first end of the second semi-cylinder 220 is connected to the first end of the second hand-held part 110; when the first hand-held part 120 and the second hand-held part 110 are in an open state, the first semi-cylinder 210 and the second semi-cylinder 220 are clamped into a cylinder 200, and when the first hand-held part 120 and the second hand-held part 110 are in a closed state, the first semi-cylinder 210 and the second semi-cylinder 220 are separated and opened; the first end of the puncture member 300 is conical, and the second end is provided with a clamping part 310, and the clamping part 310 is used to be clamped by the first semi-cylinder 210 and the second semi-cylinder 220. By providing the first hand-held part 120, the second hand-held part 110, the first semi-cylinder 210, the second semi-cylinder 220 and the puncture piece 300, the operation is convenient, safe and reliable, and the success rate and safety of thoracic and abdominal catheterization can be effectively improved. At the same time, after the puncture piece 300 is taken out, the first semi-cylinder 210 and the second semi-cylinder 220 are clamped into a cylinder 200, which facilitates the insertion of the catheter and prevents the catheter from being taken out when the device is withdrawn.

[0039] Specifically, the first hand-held part 120 and the second hand-held part 110 are long strip-shaped parts. The second hand-held part 110 and the middle part of the first hand-held part 120 can be hinged by a pin. The first end of the first semi-cylinder 210 and the first end of the first hand-held part 120 can be fixedly connected; the first end of the second semi-cylinder 220 and the first end of the second hand-held part 110 can be fixedly connected. The cylinder can have a hollow channel for clamping the puncture member 300, which is used to pass the catheter after the puncture is completed. By clamping the second ends of the first hand-held part 120 and the second hand-held part 110, the first ends of the first hand-held part 120 and the second hand-held part 110 are tightened, and then the first semi-cylinder 210 and the second semi-cylinder 220 are clamped into a cylinder 200.

[0040] As a specific example, the clamping portion 310 is an annular groove provided on the piercing member 300 , and the diameter of the groove wall on both sides of the annular groove is greater than the diameter of the cylinder 200 .

[0041] Specifically, the depth of the annular groove can be greater than or equal to the wall thickness of the cylinder 200, and the length of the annular groove can be the length of the cylinder 200. The groove wall of the annular groove is used to limit the front and rear positions of the piercing member 300 to prevent the piercing member 300 from sliding in the cylinder 200.

[0042] As a preferred example, the cylinder is conical, the first end of the cylinder 200 is close to the first hand-held part 120 and the second hand-held part 110, the second end of the cylinder 200 is far away from the first hand-held part 120 and the second hand-held part 110, and the diameter of the second end of the cylinder 200 is smaller than the diameter of the first end of the cylinder 200.

[0043] Specifically, the tapered cylinder 200 is easy to insert into the patient's thoracic and abdominal cavity. During insertion, the second end of the cylinder 200 is first inserted into the patient's thoracic and abdominal cavity, and the first end of the cylinder 200 may not be inserted into the thoracic and abdominal cavity.

[0044] As a preferred example, a traction rope is provided at the second end of the puncture member 300. The traction rope can prevent the puncture member 300 from falling off and penetrating into the patient's thoracic and abdominal cavity, and is also convenient for withdrawing the puncture member 300.

[0045] As a preferred example, a booster 320 is provided at the second end of the puncture member 300. The booster 320 can be a cylindrical handle, which is convenient for medical staff to forcefully pierce the puncture member 300 into the patient's chest and abdominal cavity.

[0046] As a preferred example, a guide wire 400 is further included, and a through hole is provided at the center of the puncture member 300, through which the guide wire 400 passes. This makes it convenient for medical staff to operate and improves the accuracy of puncture.

[0047] As a preferred example, either the second handheld portion 110 or the first handheld portion 120 is further provided with an adjusting member 130, which is used to adjust the angle of the first handheld portion 120 and the second handheld portion 110. When the opening and closing angles of the first handheld portion 120 and the second handheld portion 110 are in a fixed state, pressing the adjusting member 130 can unlock the opening and closing angles of the first handheld portion 120 and the second handheld portion 110. The adjusting member 130 refers to the opening and closing method of the existing posterior cranial fossa retractor, which is a prior art and will not be described in detail.

[0048] As a preferred example, when the puncture member 300 is clamped on the cylinder 200, the outer surface of the puncture member 300 and the outer surface of the cylinder 200 form a smooth curved surface. This can effectively reduce the damage to the patient's skin during the puncture process and improve the comfort and convenience of the puncture.

[0049] As a preferred example, a first hand supporting portion is disposed at the second end of the first hand holding portion 120 , and a second hand supporting portion is disposed at the second end of the second hand holding portion 110 . The first hand supporting portion and the second hand supporting portion are used to assist in opening the cylinder 200 .

[0050] As a preferred example, an angle adjuster is also provided, which is provided at the hinge of the first hand-held part 120 and the second hand-held part 110, and is used to adjust the angle between the puncture member 300 and the first hand-held part 120 and the second hand-held part 110. In order to adjust the puncture angle of the puncture member 300, the angle adjuster here refers to the angle adjuster commonly used in folding sofas in the prior art, such as Japanese buckles, as long as the angle adjustment can be achieved. The angle adjuster can effectively fix the angle between the hand-held part and the semi-cylinder, and improve the convenience and applicability of puncture.

[0051] It is known from common technical knowledge that the present invention can be implemented by its embodiments without departing from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
