Description

Technical Field

[0001] The invention relates to the technical field of thoracentesis instruments, and in particular to an anti-blocking and anti-displacement pneumothorax puncture trocar. Background Art

[0002] Pneumothorax is a common combat injury, which is divided into tension pneumothorax and open pneumothorax. The main causes of injury are artillery shells, gunshot attacks and vehicle accidents. On the battlefield, tension pneumothorax is mainly caused by penetrating chest (back) injuries (gunshots) and contusions (vehicle accidents). Penetrating chest (back) injuries caused by gunshots are generally accompanied by lung tissue damage. After the narrow chest wall wound is naturally or mission-closed, air continues to escape from the ruptured lung lobes into the pleural cavity, forming a tension pneumothorax. Chest (back) contusions caused by vehicle accidents can directly cause tension pneumothorax.

[0003] Tension pneumothorax is a common preventable war-related fatal injury, but simple tension pneumothorax rarely occurs in actual combat. Open pneumothorax occurring on the battlefield is generally accompanied by lung tissue damage and pleural hemorrhage. Currently, pleural puncture decompression is the most commonly used and effective technology for treating tension pneumothorax in a tactical environment. In the emergency treatment phase, our army requires the use of a "puncture needle with a one-way drainage tube" to puncture and exhaust tension pneumothorax, which needs to be accompanied by appropriate drainage after puncture. Conventional puncture equipment is prone to displacement after puncture, resulting in detachment or secondary damage to the lung lobe. In addition, traditional puncture and drainage cannulas are prone to blockage when subjected to chest wall and intracavitary pressure. At the same time, due to the different physical conditions of the wounded, the depth of pleural puncture needs to be reasonably controlled to avoid secondary trauma. Therefore, the puncture equipment for pleural puncture in battlefield emergency treatment needs to meet the above requirements.

[0004] At present, the puncture equipment for pleural cavity puncture cannot take into account both puncture and drainage, cannot grasp the puncture depth and timely selection, and cannot effectively retain to prevent displacement causing secondary trauma and dislocation, and is not suitable for battlefield emergency use. Summary of the invention

[0005] In view of the above problems existing in the prior art, the present invention provides a pneumothorax puncture trocar with anti-blocking and anti-displacement function, which effectively solves the problems existing in the prior art pneumothorax puncture equipment by combining puncture depth positioning with anti-blocking and anti-displacement designs.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] A pneumothorax puncture trocar with an anti-blocking and anti-displacement function, comprising a trocar, a functional seat and a needle seat, wherein the rear of the trocar is provided with a movable and lockable functional seat, and the end is provided with the needle seat in an integrated manner;

[0008] The trocar needle comprises a three-layer structure of an outer sleeve, a support layer and an inner core. The front and rear ends of the outer sleeve are both provided with slots, air holes are provided between the slots at the front end, and scale lines are marked at the rear end. A relatively movable support layer is provided inside the outer sleeve and is controlled by a functional seat.

[0009] The front and rear ends of the support layer are both annularly distributed, and the sliding support parts and functional support strips correspond to the slot positions. The front and rear ends of the sliding support parts and the functional support strips are respectively provided with protrusions that pass through the slots. The protrusions on the rear sliding support parts are connected to the functional seats on the outer sleeve. The functional seats are slid forward to make the front functional support strip pass through the slots and arch.

[0010] The front end of the inner core is a puncture end, and a strip-shaped ventilation groove is arranged at the front side of the inner core corresponding to the position of the ventilation hole.

[0011] Furthermore, the scale marks at the rear end of the outer sleeve are 4 cm, 5 cm and 6 cm scale marks, respectively, and are marked with numbers or different colors.

[0012] Furthermore, the slot positions at the front and rear ends of the outer sleeve are staggered and not on the same straight line, and the length of the slot at the rear end is 2 cm.

[0013] Furthermore, the functional seat includes a movable sleeve and a locking ring installed on the rear side of the movable sleeve. The rear end of the movable sleeve is a forked portion with a gradually thickening inner wall. The outer wall is provided with threads and a locking ring that matches the threads is installed. The functional seat is fixed to the outer sleeve by screwing the locking ring backward.

[0014] Furthermore, the protrusion on the sliding support portion passes through the slot and is connected to the functional seat, and slides relatively with the functional seat. The protrusion of the functional support strip is located at the front end, passes through the slot and abuts against the front end of the slot to limit the position.

[0015] Furthermore, the width of the sliding support portion is greater than the slot of the outer sleeve, and the sliding support portion can completely cover the slot of the outer sleeve to achieve sealing during the relative sliding process.

[0016] Furthermore, a one-way valve is installed at the needle seat end.

[0017] Beneficial effects of the present invention:

[0018] The anti-blocking and anti-displacement pneumothorax puncture trocar of the present invention comprises a trocar, a functional seat and a needle seat, wherein the rear of the trocar is provided with a movably lockable functional seat, and the end is provided with the needle seat in an integrated manner; the supporting layer of the trocar is connected with the functional seat, and the functional seat is slid forward so that the front functional support strip passes through the slot and arches, and at the same time, a scale line with a limited depth and a vent hole cooperating with the vent groove of the inner core are marked on the outer sleeve;

[0019] The anti-blocking and anti-shifting pneumothorax puncture trocar of the present invention can intuitively know the puncture depth by adjusting the functional seat and extending the functional support strip from the slot arch. At the same time, the movable functional seat is moved to the corresponding position for fixing. The extended functional support strip can limit the entire puncture trocar from displacement and falling off or deep damage to the organ.

[0020] The anti-blocking and anti-displacement pneumothorax puncture trocar of the present invention has ventilation holes and ventilation grooves on the outer sleeve and the inner core. Under the action of the support layer, the trocar is ensured not to be blocked to exhaust the pneumothorax, and the exhaust effect and efficiency are increased.

[0021] The anti-blocking and anti-displacement pneumothorax puncture trocar of the present invention effectively solves the problems existing in the existing pneumothorax puncture equipment by combining puncture depth positioning with anti-blocking and anti-displacement designs.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
