Suture Equipments TRIZ Cases

Rigid cortical screws can limit flexibility after syndesmosis injury; flexible anchors and a tensioning delivery device support healing motion.

A proximal-head opening secures elastomeric devices and supports intra-operative reattachment during surgical procedures.

An expandable proximal anchor increases a prostatic implant’s urethral-side footprint to retract tissue and relieve constriction.

Multiple anchors on a shared tether enable catheter-guided tissue contraction when direct visibility of the target is unavailable.

Constrained hip access and knot tying complicate labrum repair; a self-locking anchor enables direct acetabular attachment with less trauma.

Flexible sutures and separate distal and proximal anchors close annulus fissures with adjustable tension while preserving the disc nucleus.

To overcome short antimicrobial action, layered coatings combine direct and microcontainer-loaded antibiotics for fast and sustained release.

Manual navigation in small tubular anatomies can be slow and risky; automated paths, image fusion, and EM tracking improve needle placement.

See how a shuttle transmitter and receiver pass a suture through tissue for precise, repeatable stitching in confined surgical spaces.

Manual sternotomy wire twisting can loosen over time; a woven shape-retaining cable forms a twist lock to maintain bone-securing tension.

Medical coating polymers often trade conformability for degradation; a 10–60% polyalkylene glycol fraction and controlled crystallization balance both properties.

Bilaterally articulated tooling creates straight or angled bone tunnels that restore tendon or ligament insertion areas and support osteointegration.

Nested needles and lever selection support precise, gentle closure of the annulus fibrosus incision after nucleus pulposus removal.

Fluid obscuration and tissue closure hinder eye-wound suturing; a transparent projection stabilizes the wound and clears the view.

A rotatable curved needle enables continuous suturing across wide incisions, shortening procedures and minimizing residual foreign matter.

Single-scope delivery positions magnetic assemblies accurately for larger anastomoses through minimally invasive access.

Two suture buttons and an inserter position a flexible implant across ankle bones for robust fixation with simpler surgical handling.

A minimally invasive device captures the mitral leaflet and positions artificial chordae in a beating heart, reducing trauma during repair.

Manual suture knotting can prolong surgery and demand high skill; this device compresses the suture for reliable automated locking.

An integrated piercing anchor penetrates the prostatic capsule and deploys a tail to compress prostate tissue and relieve urethral constriction.

Two jaw pairs anchor a lesion and the lumen wall to provide stable traction for endoscopic submucosal dissection.

Compressing cancellous bone around a spinal anchor improves fixation strength while avoiding penetration of the distal cortical wall.

A high-density knotless anchor array uses independently tensioned suture stitches to secure tendon to bone with less micromotion.

Alternating mesh regions keep the cog thread fully contacted, limiting pushing and loosening during subcutaneous insertion.

Subjective pain-based rehabilitation measures vary by patient; a resonant implantable sensor provides quantitative wireless suture-tension feedback.

Multiple teeth at the distal anchor-delivery channel grip the implant’s inner wall to limit twisting and warping during annuloplasty anchor deployment.

A load cell feeds real-time tension data to an actuator, helping control suture force and reduce rupture risk during valve repair.

Adjustable cutting gates, clamps, and drill guides shape a meniscal graft and tibial site for precise alignment without manual measurements.

A detent-controlled anchor driver and suture guide enable one-handed soft-tissue fixation with precise positioning and shorter procedures.

Separating the rotating anchor from the suture insert supports firm bone coupling without twisting pre-attached suture threads.

An edge-to-edge catheter system applies multiple sutures to deteriorated mitral flaps and removes badly positioned points during percutaneous repair.

Traditional bone reference pins can loosen or obstruct orthopedic procedures; temporary suture anchors secure markers while limiting drilling damage and post-surgery risks.

Traditional knot tying can limit repair strength and slow soft-tissue-to-bone procedures; braided tubular sutures form adjustable loops for consistent tension.

Manual stitching and trimming can compromise allograft connections to bone fixtures; a spiral drive advances needles along a defined path.

An inflatable member compresses a collagen patch against tissue, simplifying placement while supporting biological integration during repair.

Segmented bending pairs artificial muscle and wire actuation to improve maneuverability, kink-resistance, torque transfer, and treatment access.

Closing jaws deliver a needle between them for precise suturing in hollow organs, reducing manual manipulation and supporting more efficient treatment.

A locking feature retains repair-suture tension during shuttling, simplifying knotless valve attachment and supporting a fluid-tight tissue seal.

Deployable molly anchors and bone plates help reapproximate separated sternum sections, addressing inefficient closure and insecure fixation after surgery.

A mechanical-advantage suture helps arthroscopic graft fixation apply substantial force while improving tension control and attachment stability.

Anchors and adjustable tethers reposition ventricular tissue to reduce remodeling and support valve function through a less invasive repair approach.

Deployable anchors and a self-contracting lock ring close vascular access holes while reducing procedure time and blood leakage.

Collagen patch repairs can complicate integration and degradation; an expandable member applies controlled compression while supporting healing.

Knots and crimps complicate cardiovascular repair; a shuttle suture and locking feature retain repair-suture tension for secure implant attachment.

See how transcatheter pads engage papillary muscles and use sutures to improve valve coaptation without cardiopulmonary bypass.

A helical bone implant uses notched pillars to add flexibility while maintaining strength and reducing movement limits after surgery.

Replacing drill-guide handoffs and hammering, the inserter creates a precise bone hole before placing the suture anchor with less tissue trauma.

Controlled zinc biocorrosion helps wound closure devices balance mechanical strength, tissue compatibility, and resorption without removal surgery.

An anchor-and-tether assembly creates a urethral hammock without abdominal or vaginal incisions or permanent mesh, enabling outpatient treatment.

A proximal needle-head opening holds elastic or flat members securely and supports intraoperative reattachment after separation.
