Description
Technical Field
The invention belongs to the technical field of medical auxiliary instruments, and particularly relates to a single-end suturing device of a nasal endoscope.
Background
The operation of removing lesions from the saddle area under the nasal nerve endoscope has the advantages of no need of pulling normal brain tissues and no need of craniotomy, and has wide application prospect. However, the lesion excision operation through the saddle area of the nasal endoscope can be performed only through an operation channel with the length of about 7 cm-10 cm and the diameter of about 1.5cm, so that the suture and knot tying of the skull base dura mater are difficult to be performed by using a traditional needle and a traditional thread in the narrow and deep operation channel, and the leakage of cerebrospinal fluid after the operation is the most serious and uncontrollable complication in the saddle area operation through the nasal endoscope.
The dural suture of the skull base of the nasal endoscope does not need watertight suture like craniotomy, only needs to change high-flow leakage into low-flow leakage, and simultaneously gives a certain supporting force to the skull base, thereby avoiding the nasal leakage caused by hernia under the filling due to pressure. The main difficulty of the current endoscopic nasal dural suture is knotting after pre-suture, and although the endoscopic nasal dural suture can be realized after training for a certain time, the endoscopic nasal dural suture needs a great deal of time and is not easy to master by most doctors.
The traditional mode of stitching knots is to operate on both ends of a wire, with different winding modes to knot the "ends" of a wire. The suturing and knot-forming mode has the advantages of firm knot formation and difficult loosening, and has the defects of large required operation space, multiple operation steps and difficult completion in the nasal cavity.
According to the characteristics of nasal cavity suture knot, a single-end suture knot-tying device under a nasal nerve endoscope is developed, the traditional operation at two ends of one wire is changed into operation at one end of one wire, and meanwhile, the knot-tying is further completed by using a clip, so that the method saves time and is easy to master. The clip can be made of two materials, one is made of titanium alloy material and the other is made of absorbable material, and the principle is that one end of a suture is made into a preset knot in advance, after the suture is finished, the tightness of the suture is controlled by pulling the suture, and then the clip is fixed on the suture by using a clip holder, so that the aim of forming a complete knot is fulfilled. However, because the nasal cavity operation space has a certain limit, the volume of the used suture clip is smaller, and the opening and closing operation of the clip is relatively fine and has a certain difficulty.
Accordingly, the present application proposes a rotatable transnasal endoscopic single-ended suturing device that facilitates controlling the opening and closing of a clip to solve the above-mentioned problems.
Disclosure of Invention
The invention aims to solve the problems that the opening and closing operation of a clamp is relatively fine and has certain difficulty due to certain limitation of an operation space when the skull base dura mater suture is performed by adopting a single-thread suture mode. The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. It should be understood that this summary is not an exhaustive overview of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.
The technical scheme of the invention is as follows:
the utility model provides a single-ended suturing device of intranasal scope, including the sleeve pipe, the fastener, the connecting rod, the nut, translation piece and spring, the fastener is installed on the sleeve pipe, the intraductal translation piece that is provided with of cover, the connecting rod passes the sleeve pipe and is established with the translation piece and be connected, the one end and the spring of translation piece establish to be connected, the other end and the handle of fastener of translation piece are connected, the other end of spring is installed on sheathed tube inner wall, the connecting rod includes the polished rod, threaded rod and shifting block, the bottom of polished rod is connected with the threaded rod, polished rod and threaded rod integrated into one piece, the other end of polished rod is connected with the shifting block, shifting block and translation piece peg graft, sheathed tube bottom rotation is provided with the nut, nut and threaded rod threaded connection.
Further, a spring piece is arranged on the wire clamp, and the spring piece is respectively connected with the two handles on the wire clamp.
Further, anti-slip teeth are machined on the inner sides of clamping pieces of the wire clamps, the clamping pieces of the wire clamps are used for clamping suture lines, and wire knots are arranged at the other ends of the suture lines.
Further, a first rack is machined on the handle of the wire clamp, a second rack is machined at one end of the translation block, and the first rack of the wire clamp is meshed with the second rack of the translation block.
Further, the intraductal bull stick that rotates that is provided with of cover, the one end of bull stick passes the sleeve pipe setting in the sleeve pipe outside, and the other end of bull stick is established with the fastener connecting piece and is connected, and the connecting rod rotates and sets up in the bull stick, and the bottom of fastener connecting piece contacts with sheathed tube tip, is the cavity in the fastener connecting piece, and the translation piece passes through the spring to be connected with the inside wall of fastener connecting piece, and processing has the jack on the fastener connecting piece, and the fastener passes through the jack grafting on the line clamp connecting piece.
The invention has the following beneficial effects:
according to the single-end suturing device for the transnasal endoscope, provided by the invention, under the condition that the threaded rod is connected with the nut in a matched manner on the connecting rod, the shifting block is driven to move up and down in the translation block, so that the translation block is controlled to translate left and right, when the translation block translates to the wire clamp, the clamp end of the wire clamp is driven to be opened by extruding the handle of the wire clamp, the wire clamp is moved to a suture thread, the handle is opened under the action of the spring piece under the control of the reverse movement of the translation block to the wire clamp through the connecting rod, the clamp end of the wire clamp is closed, the suture thread is clamped and knotted, the accurate control of opening and closing of the clamp can be realized on the premise that the threaded rod is connected with the nut in a matched manner, and the difficulty of knotting the end part of the suture thread is reduced after the single-line suturing of the transnasal endoscope is completed.
According to the single-end suturing device of the transnasal endoscope, one end of a suture is made into a preset knot in advance, and after the suturing is finished, the knot can be formed through single-end operation of the suture. The traditional method of operating at two ends of one wire is changed into a method of operating at one end of one wire into a knot; the knotting is further completed by using the wire clamp, so that the method saves time and is easy to master. The wire clamp can be made of two materials, namely a titanium alloy material and an absorbable material; the nasal cavity operation space has certain restriction, and the suture clamp volume that uses is less, and the operation of opening and close of fastener is relatively meticulous and has certain degree of difficulty, consequently can drive the fastener connecting piece rotatory through the bull stick, improves the operation flexibility ratio of fastener.
